I just tried using GridMove and it is a wonderful tool!
I even created my own custom grid that splits a screen into 4 basic parts, but the closer to the corners you go, the larger your window will be… allowing me to have corner windows at 50%, 75%, and 95% of the screen (yeah they overlap above 50% but that is what I wanted).
I found a bug where real-estate driven ‘follows mouse’ focus from TweakUI was confusing the tool and I posted a message in the forum.
An hour or two later the developer updated the code and it’s all fixed! Now THAT is service! Folks, please consider donating in support of this tool, it’s clearly worth it to me.
Now to put my money where my mouth is… make a donation myself!
