Bug: If in forum ID, where turned on this hack, thread not have thread prefix so... when we browse main forum page (home page) we can see at column Last post this thread name + prefix from first thread in forum. Thread without prefix are sticky and for this thread on forum home page will add prefix from first thread in this forum that have prefix. So, on main page this hack add prefix, but currently this thread doesn't have prefix.
Future suggestions:
1) add AJAX prefix change when browse forumdisplay.php (like we can change thread title with mouse double click)
2) store all prefix names in DB. And if we rename one prefix this changes will automatically apply for all threads that have this prefix
3) ability to customize which prefixes can be used/displayed for which forums ID. It's need for faster page loading. For example: I have around 50 prefixes, but at some forum ID I will use just 2-3 prefixes and other prefixes not needed. At this moment, this hack display all prefixes and it's increase page size and page loading.
PS: I'll be happy if it be done in one of future versions of this hack

If not, I'll must uninstall this hack and do this prefixes manually
