They also don't remember that you've done a search, or opened the map key, or the export tab, or any number of other things.

I think this is also a duplicate of point 3 on https://trac.openstreetmap.org/ticket/4850 though it's a bit hard to parse that.

My bug report is the clearest of them all.
The user clicks cycle map, that is remembered in a permalink he then creates.
Same with the other map types below it.
But then when he adds one of the checkboxes right below them still... sorry, not included in the permalink.

The notes layer is now persisted by [changeset:a7e6784/rails]. We don't think it would be appropriate to persist the data layer because previous experience tells us that it's very easy for people to unintentionally give out links which have the data layer on and the user experience when visiting those links is poor and also expensive in terms of server resources.

Replying to [comment:5 TomH]:
OK, but then when they turn on a layer which you aren't going to deliver, then 1) hide the permalink, or 2) pop up some alert upon click telling them what's (not) going to happen. Also let them know how to make such a permalink just in case they really really want to.
