Sunday morning practice

Was thinking of something and came up with this.

The refresh icon's and the trigger icon's position can be interchanged. The placement used in the shot is for a right-handed person. The positions can be switched such that a left-handed person can use the app with ease. The idea is to be able to use the app entirely, with only a single hand (eg. You're on the train, standing and holding onto something for support, while quickly checking out some data on this app).

The user can use a flick or single tap gesture on the trigger button and reveal the bottom panel.

What do you folks think? Let me know. (Be it interactions, interface, idea, Pokemon, Eggs on toast? )
