Window Positioner

I've tried several extensions to save the positions of your different Chrome windows. I love that you can save specific websites for each window. So far this one is the most straightforward and probably the one I will keep using. HOWEVER, each and every of these extensions I've tried has the same problem: The opened windows don't stick to the side of the screen. They're always offset by ~2mm in the corners and it's really annoying (same problem the previous reviewer had). But I suspect it's probably an issue with Chrome itself and its permissions. If anyone knows how to fix this, you'd be a lifesaver! Also, the "This extension may soon no longer be supported because it doesn't follow best practices for Chrome extensions." worries me a bit...

It does not start at the exact 0 position from the desktop. There is always some padding area which is about 5 pixel length for the starting X position and the end of Y position. I tried to input - value like -100 for X and 9999 for Y but it won't change anything.

This does exactly what it should, it's an amazing addon that I just discovered, the only little feedback what I have is a "test position" button
