– This may be a bug, I’ll check it out, thanks!
– Please be sure to add the layouts you want to appear onscreen, to the first list in Settings -> Layouts, called “Manual arrangement”. Layouts there should change color to a light blue. This means that they will be appearing while dragging.
– Please be sure to set “Action for old windows” to “Minimize” in Settings -> Snapshots. You can also try to restore again the snapshot right after the first time. I’ll have a look at it however, thank you for your feedback!
