Can you PLEASE add a option in settings which remove the "minimize/maximize button" (near the Close button) ?
I did missclick it, and now maximized mapster is bugged , where I can't minimize it again, becuase the top frame is out of frame. Like you have black bars on bottom + right, and whole window is out of frame

FEATURE REQUEST : please add option remove the small arrow minimize/maximizebutton.
BUG REPORT : when you maximize the window, you can't minimize because mapster window is out of frame.

The bug is because of BlizzMove Addon (I will write this bug report there too)

Wanted to give workaround (like change the scale to smaller and then it will be in different place), but You/BlizzMove or Blizz did change something, and now it remember the position when you move it maximized, before when it was maximized and you move the window it goes right back to be out of frame, now you can grab the side(it is like 1-2pixels) and move it down to minimize it.

By the FEATURE REQUEST : please add option remove the small arrow minimize/maximize button. I still stand, would be nice to have it, but I know that it is lowest priority.

Looks like the BlizzMove author will not add "if" statment for Mapster , so here is a fix :
Go to Game Menu => Options => Addons tab => BlizzMove => List of frames => can just write write in Filter : map or world => turn off WorldMapFrame => /reload or relog
after that BlizzMove will not interfere with Mapster WorldMapFrame.
