I'm intending to try out roll20 for PbP games, where players aren't online at the same time. We post our turns in a forum and use the map for placement etc in combat.
Usually we indicate how PCs' movements take place, in case there are AoOs taken etc. For this to be reflected, grid coordinates would be really useful, since then we can reference which square we started in and ended up in (and even which squares were walked through, if need be).
Would it be possible to add X and Y coordinates at the top and side of the map? I don't think it should be too difficult, but I'm not sure how the app was coded.
