As a long-time gthumb users, I have defected to shotwell and I am mostly happy with it (if you compare the life-span of gthumb and shotwell (first shotwell commit in svn is 12 months ago), I find it very promising). Disclaimer: I am just a user of shotwell 0.5.2
-No multiple events on a day:
In an event, I select a couple images, I press Ctrl-n (or select menu->new event) and the photos are split off into a new event on the same day. Works fine here.
The import dialog *can* copy photos to a folder (I think it proposes the XDG_PICTURES_DIR which is set to "$HOME/Photos" on my box) although I recall that is going to be configurable.
There *is* a checkbox in that import dialog that says "don't copy image" which lets the image rest in place as is (making it useful for other programs). I simply copy my new pictures to a new subdir of my media dir and reimport the whole media dir with the "leave in place" option checked, which will not copy the images to a magic library. It will ignore duplicates that are already imported.
As for the obvious solution: monitoring a dir for new files to appear there is a ticket for that: http://trac.yorba.org/ticket/374
-As for zooming, that is annoying, indeed. I never noticed before. Trac tickets seem to indicate it should be there.
Overall I like it because:
- It is fast
- It doesn't get in my old ways of organizing my photos (that is keeping subdirs in a media folder where *I* put them)
- tags and events are useful
- easy integrated flickr upload
- very dynamic development and responsive team of hackers
