Post Icon Mods & Hacks

[trigatch4]

As I'm perousing threads/hacks/mods I can't seem to find anything compatible with 3.7 that does what I need. Perhaps someone can point me in the right direction or will whip something up for a few bucks?

Require Post Icon for New Thread
I've seen this for 3.6.X but nothing for 3.7.X

Filter By Post Icon
I've seen mods that SORT by post icon, although none for 3.7... I want to FILTER by Post Icon within forums and subforums so when you're in that forum and click the icon you'd like to filter by it shows ONLY those posts with that icon. I guess sorting would work too but I still have that main question of 3.7

Different Forums/SubForums Get Different Post Icons
Easy way to do this for 3.7?

Thanks in advance for your help?
