I just bought Groupy off Steam and tried it for a bit. Immediately there are very mixed feelings as the tool is not proving to be useful in the way I expect.

1. Most importantly, Alt-tab still behaves the same as before, showing all 20 open items and having me cycle through them. I imagined Groupy would help resolve this alt-tab clutter by enabling alt-tabbing between sets/groups, while using the configured hot-key to cycle between tabs of the same group.

2. Secondly, I expect the group to behave as one object for certain actions (like in the taskbar). One click minimize/maximize doesn't work for groups in taskbar. You have to go and click over one of the items of the group that appear upon hover, to maximize the group. But that same action doesn't even work for minimize.

3. In the same vein as above, There is no button for closing entire group at the top-right. You have to go to the three dot settings to do this. (I just saw that this ability is now in beta and will hopefully come in main, so that's good).

4. I created a saved group of 3 file manager tabs, and opening it from start menu collapsed the top ribbon into an unusable state. Also, after opening closing the saved group a couple times, the group stopped opening as one window, but multiple windows. However, it was not possible to add them back, as I think groupy still thought they were grouped. I fixed this by closing and restarting groupy.

Overall, this seems like a solution that could be great but is not very useful in current state. The alt-tab issue is a deal-breaker for me, so please let me know if I have missed some setting that changes that behavior.
