This userscript adds some features and fixes some issues to improve your game experience.
Feature list (excerpt)
Adds completely new chat with pm tabs, clickable links, clickable usernames (to send a pm), intelligent scrolling, chat command suggestions and a tutorial command (described here: https://greasyfork.org/forum/discussion/18965)
Adds smelting and tree growing timer and changes other timers to look like the ones in DHQoL for DH1
Adds calculated times until an event (like collecting sand) happened at least once with different probabilities (1%, 10%, 20%, 50%, 80%, 90%, 99%) - these information are available on hover in shovel popup and fishing rod popup (for all types of fish - can be seen here: http://imgur.com/a/ElG0g)
Adds information (instead of the text "1") for some bound items: capacity for furnace, oil cap for oil storage, tier level for tools, oil production for oil items and current state for boat/canoe
Adds requirement tooltips for recipes
Hides furnace, oil storage and oven recipes if they aren't better than the current level
Hides recipes of maxed machines or owned items which are not stackable
Detects spamming in chat and hides spam messages (may be obsolete since the server has some spam detection)
Fixes updating the brewing and cooking recipes

lots of improvements/fixes for chat:
removed vulnerability for zalgo text
fully restored copyability of the chat messages ("Server Message"s are select-/copyable again)
added chunk system for chat to improve responsiveness of the whole page with a long chat (activates at more than 900 messages):
Groups chat messages in chunks (technically divs) to hide non-visible chunks and un-hide them on scrolling through the chat. This introduces important performance reduction (e.g. for reduced power consumption).
Though it is so far only tested in Google Chrome. Please inform me about occurring problems via reddit: /u/TheZorbing.
