I’ll chime in I suppose, as the feature request my request was tracked in was recently closed as a “duplicate” of this one.
Astral’s lack of a “simple fog of war” feature a la Roll20, Tableplop, etc is literally the only thing keeping me from migrating over. Dynamic lighting is fine for people who prefer that, but I would really just prefer to have the map covered in an opaque-to-players black layer and have the option to selectively remove parts of that layer via click-drag rectangles or multiple point click polygons as they move through the dungeon.
The “put black rectangles on the map with triggers to remove them” option sort of mimics this, but it requires just as much setup as dynamic lighting which somewhat defeats the point. It also doesn’t work very well with irregular shapes like caves.
The essence of this feature request (to me) is the lack of prep needed. Just drag a map onto the play space, size it properly with the grid, and turn on the “simple fog” - done, ready to play in about 5 minutes. This no-prep option is invaluable for those of us who run sandbox campaigns or large megadungeons where we don’t necessarily know where the players will go next. It also tends to be a lot less buggy than dynamic lighting, virtually eliminating the chances of a weird clipping issue revealing half the dungeon. Any implementation that requires pre-defining rooms would somewhat miss the point, which is to just for the GM to be able to selectively hide/reveal parts of the map manually.
