Keyframes edit window on dual monitor setup?

I'm trying to use keyframes edit window on my dual monitor setup (2560 x 1440 and 3072 x 1920) and keyframes edit is very interestingly positioned:

Basically it is not possible to edit curves without undocking that part and after undocking there are are some issues with window scaling when I drag it from one monitor to another - I it is zoomed out to extent of being unusable, because some parts of window are not visible due the window size.

Am I missing some obvious way to arrange it to be more usable?

This is fixed in Beta 4.
But I still would like to have a fully customizable user interface.
