Well, nothing will change about stable implementation serie (0.8.x), because,
i have remove the gimp algorithm from the plugin and build a new one from
scratch, inspired on ImageMagick technic and supporting 16 bits images (RAW
files for example). The code will be available for 0.9.0 release (beta1 is
planed during May)
The result will be different now since the algoritms are different. To be
honest, the gimp plugin algorithm is very compicated to perform unsharped
mask (undocumented, unoptimized, etc.). The new implementation is more easy
You can test it to compile the current 'trunk' branch from svn...

Not yet. Image Editor selection usability will be improved in the future...

Yes, digikam image editor support undo/redo since a long time using Edit menu

Well, test current 0.9.0-svn, you will be surprise. There are some screenshots
taken from current implementation on web project page :
