Minimal hack that add « on the fly » the « New Thread » button alongisde of the « Reply » button on showthread when you have permission to post new threads.
We’ve seen this modifications in the templates before, but as you do not want to edit all your styles, and be forced to revert your templates and forget about this mod, it is obvious that a product is good enough.
What it does?
1- check if the forum permit new threads, like in forumdisplay
2- add a « New Post » button to the left of the usual « Reply » button when #1 is ok
The good thing is that if you have custom buttons in a style, you can edit the template named « nex_newthread_showthread » to fit your design…
