@ASH: the last part of your wish-list - using snapshots taken by the embedder directly for "any" image type and storing it to the "appropriate place" (see below) - is now mostly done in SVN r4807. Only support for software-snapshots is currently missing.

I've added a "Use as" sub-menu (as part of the image-viewer's context-menu) which offers the available actions as menu-items.

Note that this is only supported for unzipped images (= images stored in folders) because saving a file in a ZIP means to completely recreate the ZIP, which is too expensive.

"Appropriate place" means the primary image folder, that is the first one that QMC2 uses when there are multiple. When a file of that name already exists a backup (*.bak) will be created first.
