I used gThumb to help manage my bountiful image collection, but the new version 3.0.2 that comes with Ubuntu 12.10 has some changes to the interface that seems awfully inefficient.
* There is a larger margin around each thumbnail (20-30px, for 60px of non-usable space between items), no matter what thumbnail size I choose.
* The File Properties area cannot be toggled off, and it is much larger than before; furthermore, it is present even when no image is selected and thus cannot display useful information.
I would like to know how (without forking gThumb and writing new source code) to do the following:
* shrink the gap between thumbnails to something less wasteful, either as a constant ("6px margin around each thumbnail") or a percentage ("5% of thumbnail size -> 6px between 64px thumbnails, 13px between 128px thumbnails")
* eliminate the File Information part until I ask for it of the browsing interface; perhaps as something I could summon when I am looking at a single image. At the very least, the File Information part should only appear when one (and only one) image is selected in the browsing interface.
I hope I can attach an image to help indicate what I'm talking about in case I am not clear.
