Suggestion: Make features list open up, not down

In an edit tab the OpenType features list opens down, which makes it drop off screen if the bottom of the Glyphs window is near the bottom of the screen. In full screen mode the list opens upward. It would be better if the feature list always opened up just like the instances list does.

It should go up when the main window is close enough to the bottom of the screen. The menu is set up to open to the top but the system is not sticking to it. So there is not much I can do.
