There's been some argument now and then about maybe adding version

HI David,

TOPS-20 was pretty great and was a nice OS to do sys admin and systems
programming on back then. If I remember rightly you could set a
preference in a config file as to how many back versions you wanted to
keep. Saved my bacon on a number of occasions.

What is this about versions? When I save as different types of files, it
still has the photo's original number from the camera. Even if I renamed
it, it would still be "Doggy.jpg" and "Doggy.TIF." What's the problem?

Incremental saves along the way as you edit. Yielding Doggie.tif.1,
doggie.tif.2, doggie.tif.3, and so forth. There's a command to to purge
additional versions all at once, or by file, so it's easy to clean up
when things settle down.
