I’m not tied to anything at this stage, but I don’t have a lot of free time for trying different stuff. Can I install this DE alongside cinnamon, like I have with i3?

I’ve got this now, looks pretty cool, thanks! Gonna keep looking over the documentation, but I can’t quite see the particular behaviour I’m looking for. It has the snapping (and better options than Win10), but I want to be presented with the list of other available windows for snapping on the other side.
