Add-on Custom BBCode on 1.2

Xenforo should have a built-in BBCode Manager but it don't have yet. So I need a add-on that can do this because I want to insert new bbcodes.
For 1.2 ? You can post some links to them ? I try to search on Resource Manager but the add-ons that I have used don't work well, maybe because they are developed for 1.1 or TinyMCE.
