No more HTML fails and having to edit the comment again. :D
I tweaked it a bit to include all HTML tags (and only those) I actually use for comments. Great that it also works with the Floating Comment Box!

Would suggest an official change to the image tag that encourages use of alt text, though.

I'll add the alt attribute with a placeholder string at your suggestion; do you mind sharing the tags you like to use? The ones I've included are just based on my own habits.

I'm so sorry for the late reply, I only saw your question now when I was recommending this script to someone!

This is in my current version of your AMAZING script I use for AO3, Dreamwidth, and SquidgeWorld:

Shifted:

c : center
n : br
s : small

Normal:

a : a href=
b : big
g : bigger
e : em
i : img src= alt= title=
d : details
m : summary
q : blockquote
s : strong
u : ul
l : li

Ignore "bigger", that's just for my Dreamwidth where I custom-CSS'd specific font sizes.

I avoid big, small, and center because they're deprecated in HTML5. Having details, summary, and list markup is a good idea, though. I'll loop those in.
