A really useful feature in my opinion would be the ability to create a custom flyout button bar.  Just like "mage portals", except allow me to put whatever I want on it.  My specific use case is to put all my wormhole teleports on it....There are so many in the game now

It would also be helpful to put the +20 dungeon teleport flyouts on the new flyout.

So...In theory, I could create one bar that is a flyout, that contained my mage portal flyouts, my wormholes, and my dungeon teleports :)
