Also, it's useful in a thread in which you only care about a limited number of users. For example, if there is a small band of folks fleeing to Mexico to escape a large purple dildo, it's nice to mark just those users, and skim over everyone else is replying with ":f5::f5::f5:", "LOL", etc.
Finally, you can use it to mark people who have been helpful in the past, such as reasonable posters in D&D, proficient experts in SHSC, and especially talented MSPainters in BYOB.
Does this work with SALR?
Yes.
Any other problems?
Threads open in other tabs/windows won't be re-colored until you reload them. Also, FYAD isn't supported.
I've heard that you might be able to get Greasemonkey scripts going in Safari and such, but I don't know anything about that.
The hide/show feature and corrected cursor were added by Alex Vidal ("avidal", alex.vidal AT gmail.com).
W. T. Snacks (of horrible internet fame) rewrote the search loop with compact, efficient XPath, thus creating revision 3. Unfortunately, it didn't quite work right, but thanks anyway!
Why didn't you use XPath?
I couldn't get it working for what I needed (regex matching on tag attributes, etc.). It's probably feasible, but I couldn't figure it out before losing interest.
EDIT: W. T. Snacks fixed it and made it clean, but that didn't work, so we went back to revision 2. :(
I can fix/improve this.
If you fix or improve the script, let me know and I'll credit you and put it on the site.
