Retain UI size and state when closing and re-opening Mayo.

[futuremotiondev]

I am using Mayo currently as my primary 3D model viewer and the interface always opens at a very small size. I also prefer to hide the left sidebar.

Unfortunately every time the application launches it forgets the window size and opens the left sidebar.

Just hoping there is a chance you could implement functionality to maintain the UI state after closing.

Appreciate all the hard work on this tool.
