3477	Allow manipulation other layers while uploading or downloading in one layer	bilbo	team	Currently, if you upload or download data, it will block JOSM, so you can't do anything else. It would be nice, if this would block only manipulation with current layer (the one that is being downloaded or uploaded) and you would be able to continue doing something else with the other layers (or download a new layer and start doing something in it)	enhancement	closed	normal		Core	latest	duplicate	background download upload
