Loving the V2, I think it's a huge step up. I do think it's lacking some really essential features, so I wanted to flag one of them here.
When working in foundry, there are many reasons I might want to export just a single layer. Parallax, layering over light sources, different map levels, etc.
In the current system, this feature would be mildly helpful. I made a post about layer groups though, this is combo would be spectacularly powerful. It would be awesome to be able to make multi-layer maps, and then right-click and export just a single layer group, just as an example. Or, as another thought, there was a cool crafting table map in the Inkarnate Discord server, it would be cool to have different special overlays that are one or maybe multiple layers that you might want separate.
I recognize this could be solved by "just remembering which layers you want to keep and temporarily disabling the others one-by-one", as I'm sure some people would suggest on other platforms, but that seems like completely unnecessary tedium.
