Well... you can also turn this around and ask yourself (ourselves) the question what the purpose of the [More Options] page is anyway? A regular member like you and me see nothing more then 2 extra options in the [More Options] page (compared to the QR), do we? Those are:
Options: [ ] Watch this thread...
--------------[ ] and receive email notifications
But obviously we need this [More Options] page as it is also used when editing an existing post.
What I am saying is that I actually like the plethora of icons in the QR, because the [More Options] button I now rarely use in XF. Whereas in vBulletin I always preferred/needed the [Go Advanced] screen. I think this is an accomplishment of XenForo really that I do not need the [Go Advanced/More Options] anymore. It is -yet again- another benefit in making posting on XenForo so much easier/quicker/natural compared to other products on the market.
