I guess that in most situations having the overlay active on a fresh tab is surprising and unhelpful, but I'm interested to hear what other people think.


I think it is useful for overlays like the notes, while the data overlay with its inherent tendency to freeze the browser when you zoom out should probably be tamed (e.g. limit it to high zooms or a “safe” amount of data. I know this depends on the RAM installed on the machine, but limiting on a hard zoom limit has disadvantages in areas with scarse data density). Maybe a warning like the one overpass turbo issues could help as well “you are about to load a huge overlay of 200MB of data, proceed anyway or shall we deactivate the data overlay?”
