Hello. I started using Eizo Screenslicer a few months ago to create virtual screen partitions on my 4k tv/monitor, but found that it was pretty limited for custom grids and didn't work with admin windows. I did some more searching and found grid move and am pretty impressed. The only problem I have is the method of moving screens to a grid. Setting it to "Use Drag Window To Edge method" is workable except, with a 4k screen, it's a long distance to the edge from some locations of the screen, and then you have to wait for it to recognize that you're at the edge. The "Use Draw With Middle Button method" doesn't work for me because I have several programs which use the middle click for 3d rotation (Google Earth, Vizio, and others).
I would like to suggest that there be a "Shift-Click" option, like Eizo uses, where you hold the shift button on the keyboard and then drag the window to the desired grid.
Thanks for the consideration and good job on the software.
