I should be able to drag the title bar of the ReCap window to move it, even when it is maximised, just like every other Windows program. Equally, when I am dragging the (non-maximised) window, up to the top of the screen, it should automatically maximise.
It should also obey the Win+Right and Win+Left Hotkeys.
Edit:
It just sometimes feels like your team is not conversant with Windows UI guidelines. I appreciate that the team wants to give a unique feel to the program, but don't let that get in the way of usability, otherwise it can easily get to feel gimicky and clunky.
For any others interested, these can be found here for keyboard-specific guidelines: https://msdn.microsoft.com/en-us/library/ms971323.aspx
