The more... button
If you press the More... button, it goes to edit a post, even if it's not your post in the first place (and if you don't have that permission, it correctly gives you an error for it)
I pressed the More... button accidentally on the way to issuing a like on a post, because I didn't initially remember how to open that menu, and it looks like a button so it naturally 'encourages' pressing... if it is going to do something, it should probably advertise the fact, and if it's a passive thing, it shouldn't encourage that fact by responding to a click...
Though, to be honest, likes should be more prominent than a submenu item if you want people to use them...
