I have used Groupy to group multiple Windows.
But Grouped Windows can't be dragged to Tiles.
Instead I must drag specific Window from the group.
But this has side effect that always this window is opened when I choose it through Tiles.
Instead I would like that Grouped Windows are opened by showing the last selected Window from the group.
Otherwise I have to use extra click all the time which destroys the purpose of all these productivity tools.
