For some reason I posted here and it got wiped.
Anyway.
There also is a issue with forum summary for collapsing or expanding categories unless you use a dark theme the image to click on has no contrast to view.
Unless you know where to hover to. But it is a up down arrow.

Plus if you are going to move some of the post options to the chevron why not move all. Then place it where those buttons are now in the lower right.
Instead of a new location on the top right that nobody is aware of.

Anyway if you wish to use font awesome icons why not change to say a Plus Minus or Hamburger (bars icon) to open close the menu.
Most people know what that means I think. if they have been using a mobile device.
Using that usb icon instead of the chevron is still confusing to me anyway.
By habit with UBB I always look to the lower right of a post for email reply quote notify etc.
As well as other forum vendors

Whatever you decide on it should be consistent with any area that allows you to expand and collapse like the forum summary categories.
