The user interface was revised to improve workflow:

An new edit function can be started without closing a prior edit.
The prior edit is kept and an undo/redo position is added.

Brightness and color functions can retain settings for processing 
multiple photos made under the same lighting.

RAW files work like other image files. Open and make edits, then save 
in the desired format (automatic copy to tiff-16 was removed).

A new option shows metadata captions and comments above each image.
These can also be edited and written graphically on the image. 

Three minor bugs were fixed.
