Make window resizable and reposition-able again

[raphaelluethy]

With the newest update to the app, it is now a big, high window tile on the right side of the screen. Would it be possible to resize and reposition the window again? As it is right now, it is too big and also on the "wrong" side (at least for my use-case). I attached a screenshot of how it looks like now on my machine.

It is different with the behaviour of the slash command, where the window shows up on the bottom left and is small:

I agree. We'll improve on this. Thanks!
