OK despite a warning maps works on phones and tablets.. It’s a little awkward but usable. Hmmmm?
Yes, although I think that's an issue with most VTTs. It also just depends on how much you want to depend on automation, for example I use encounters but I track initiative manually because I find it easier. They also didn't indicate whether or not the game log shows dice rolls or not in the maps view like they do if I'm using just encounters.
As far as maps and stuff, you can import any map you want and scaling is actually handled fairly well. Simpler than Roll20 when I tried it anyway.
