Filtering system in XThreads is very very interesting feature and very very useful feature, Yumi.
Thank you very much that you have made it in XThreads
I've tried to achieved it with PHP In Templates plugin, like in this forum:
http://mynie.6te.net/demo/forumdisplay.php?fid=32
Unfortunately, I need to put the
{$tf_filters['key']} variable directly in template. I don't know if it's secure or not. And, I can't make the input field has a "correlation" with other input field when creating new thread (
newthread template)

EDIT: Unfortunately, a user still can jump directly to the "latest" URL
