  213. 	// CHANGELOG:
  214.  
  215.     // **VERSION 4.0.3c**
  216.     // **ADDED:** Preview current directory index source: click the double-caret icon in the sidebar stats footer to toggle preview.
  217.     //    This is useful for server configurations that include information in addition to the index itself and is quicker than opening a separate "View source" tab.
  218.     // **FIXED:** An issue with content display caused by the fix for pdf display in the previous version.
  219.     // **FIXED:** Up directory navigation didn't correctly account for invisible files and directories when selecting previously selected directory.
  220.     // **FIXED:** More issues with prepping "pre"-type index pages.
  221.     // **FIXED:** Some issues with Error page display.
  222.     // **FIXED:** Various minor styling issues.
  223.     // **CHANGED:** Moved "Disable Text Editing" menu item to top level.
  224.  
  225.     // **VERSION 4.0.2b**
  226.     // **FIXED:** Pdf display (I hope).
  227.  
  228.     // **VERSION 4.0.1b**
  229.     // **FIXED:** Audio files weren't being loaded.
  230.     // **FIXED:** Script would fail if a file name included a special regex character `[\^$.|?*+()`.
  231.     // **FIXED:** Various issue with parsing "pre"-type index pages.
  232.     // **IMPROVED:** Sorting and display of items with names beginning with white spaces.
  233.     // **IMPROVED:** More efficient and robust index type detection.
  234.     // **ADDED:** Sorting for previewed directory contents. Initial sorting is the same as the parent's current sort pref.
  235.     // **ADDED:** Custom icons and numbering for previewed directory contents.
  236.     // **ADDED:** Append some server info and other provided information to the stats footer.
  237.     // **NOTE** that there is an issue with Chrome and pdf files.
  238.  
  239.     // **VERSION 4.0.0b**
  240.     // Numerous additions, improvements, and massive internal changes. Virtually no line of code has been left untouched.
  241. 	//      **"b" === "bugs" likely. Updates will be coming.
  242. 	//      **IMPORTANT:** This version uses a new format for user settings in the code; you will have to re-enter your defaults manually after updating.
  243. 	//      - Do NOT use exported settings from any earlier version of the script.
  244. 	// **NEW:** Added independent text editor pane.
  245. 	// - Invoke with Cmd/Ctrl + E, or in main menu > Text Editing > Toggle Text Editor", or under "Show Details".
  246. 	// - To prevent loss of work (and for convenience, e.g., to refer to a file while writing), previously entered text will not be cleared when the "New" button is clicked again, when the "Close" button is clicked, or when a sidebar item is selected.
  247. 	// - Use the Save button to save the text as a text or html file, which can be previewed and edited as usual by navigating to its saved location.
  248. 	// **ADDED:** Option to number index items, with new user setting.
  249. 	// **ADDED:** Stats footer in sidebar showing dir and file count.
  250. 	// **ADDED:** Icons for shortcuts menu to indicate local vs. remote links.
  251. 	// **ADDED:** Text editing: Clear button to empty text editing pane.
  252. 	// **CHANGED:** Text editing: Github styling customizations: Make table cells top-aligned, darker blockquote text color.
  253. 	// **IMPROVED:** Text editing: When saving rendered HTML, header uplinks will be removed.
  254. 	// **IMPROVED:** Text editing: Don't close other previewed content when making new text editing pane.
  255. 	// **IMPROVED:** Text editing: Much improved warning system for edited text: now uses `postMessage` to communicate between iframe and parent.
  256. 	// **IMPROVED:** Content display: use the same code to prep and style directory contents in the preview pane.
  257. 	// **IMPROVED:** Live sorting of grid items (but images and fonts are still sorted separately).
  258. 	// **IMPROVED:** Image zoom positioned accurately under click.
  259. 	// **IMPROVED:** Better handling of 404 Errors (Page not found): server error message will appear in sidebar, warning icon in content pane.
  260. 	// **IMPROVED:** File URLs: If a file URL (instead of a directory) is entered directly in the browser URL bar, the parent directory will be loaded instead and the file automatically selected.
  261. 	//      **IMPROVED:** Navigation: modifed highlighting styles to show when a non-audio item is selected for navigation vs. when it is loaded in preview pane but not selected (e.g. click a directory and then click an audio file; the directory item will be dimmed).
  262. 	//      **IMPROVED:** Audio: Greatly simplified shuffle play code and fixed several bugs; shuffle list now correctly updates when individual audio tracks are checked or unchecked.
  263. 	// **CHANGED:** Moved scale buttons and prev/next image buttons to preview title bar.
  264. 	// **CHANGED:** Sort by "Name" always sorts files and directories together; "Default" sort always keeps files and directories separate.
  265. 	// **FIXED:** Text editing: Some issues with split-pane resizing.
  266. 	// **FIXED:** Cmd/Ctr+W (close) should work now: previewed content will be closed first, then audio, then the browser tab itself.
  267. 	// **FIXED:** Don't autoload audio cover art when next audio track begins; i.e., leave open whatever file is being previewed, including cover art or lyrics.
  268. 	// **FIXED:** An issue with sorting by size.
  269. 	// **FIXED:** An issue with the user UI font setting.
  270. 	// **FIXED:** Navigation by typed string now correctly scrolls directory list.
  271. 	// **OTHER:** Many small style fixes and tweaks. Among others, make the previewed image and image grid background color light in default theme.
  272. 	// **INTERNAL:** Complete code overhaul.
  273. 	// - Completely rewrote the code that preps the served directory index for processing by the script.
  274. 	// - Completely rewrote and simplied the sorting code.
  275. 	// - Alphabetized User Settings for easier editing.
  276. 	// - Fixes for additional server index configurations.
  277. 	// – Performance improvments (e.g., removed multiple calls to various functions, reduced initial DOM manipulation, etc.).
  278. 	// - General code cleanup (e.g., removed unused variables and unnecessary globals, named many formerly anonymous functions, fixed numerous syntax errors, etc.).
  279. 	//
  280. 	//      **STILL TO COME:**
  281. 	//      - Dark mode for text editing.
  282. 	//      - Additional code cleanup, and more.
