[OSM-talk] JOSM wishlist: forget and undo download

[Lars Aronsson]

Sometimes I download a little too much into JOSM. I don't know the 
default memory size for the JVM, but my machine only has 512 MB 
RAM anyway and JOSM starts to get slow when I edit .osm files that 
are larger than 5.5 MB.  If I edit things in one region, such as 
one half of a city, or an island near a mainland coast, I 
sometimes download parts of the mainland or other half of the city 
by mistake.

This is when I wish I could "undo" one download batch.  Or make 
JOSM "forget" that it downloaded an area that I select.

I could in theory simulate this by saving the .osm file, use a 
text editor to edit out the objects from that area, and load the 
.osm file into JOSM again.
