A method to remove downloaded data from RAM but without sending it for deletion

[rjmunro@…]

When you load a large area into JOSM, it gets slow. It would be convenient to be able to remove a selection from JOSM without removing it from Open Street map itself. It should be possible to use either drag-selection or the search tool to choose what to be removed.

A "forget data" action has been added in a preview release not yet in the JOSM SVN:

I will commit the change after making some changes that have been suggested.

don't forget the undo-buffer of the edit-layer when clearing stuff out ;-)

maybe an option "clear undo-buffer" will help too, as there can be an vast amount of memory held captive.

Ticket #3979 has been marked as a duplicate of this ticket.

I also would like this enhancement.

what happened the last 3 years ?
Would be nice to just open a part of the osm as new layer.
