When I first dipped my toe into installing add-ons, I was very surprised that there was no way to install an add-on via web interface much as I had been used to with SMF.
Are there any plans to introduce something like that or not? Does it bother you that XenForo doesn't allow it? (Or am I missing something pretty fundamental?)
Disclaimer: I do development work on a free forum package. I do also have a live XenForo forum too.
