Hi, I think a really handy feature that could be added to groupy is to be able to arrange or tile the windows belonging to a group. So for example, I could have a group with 2 different messaging apps laid out horizontally tiled side-by-side in the one group called "Messaging". Windows has pretty poor support for this sort of tiling functionality. You can use Win+Arrow (left/right) to snap an app to the left/right top/bottom of the screen, but even that support is broken on displays oriented in portrait mode, and there's no way to "group" those side-by side apps.
Also as a more general feature request, consider that some users use displays in portrait mode. Pretty popular with coders/devs and writers. DeskScapes does not play ball particularly well with this sort of arrangement, and the screensaver functionality in particular doesn't work if you have multiple monitors arranged in a non-rectangular arrangement (ie, 1 landscape, 1 portrait, or even 2 landscapes that have a non-rectangular virtual layout. Eg. Side by side, but one slightly higher than the other.
