Thanks!
BTW, for Issue 1, the preloading bug… preloaded image is also "lost" when you move a file (pressing Ctrl+1 etc). Next image is clearly loaded again even though it is shown immediately if you press space. So moving and deleting is somehow messing up preloading. I think this is one of the major sources of "slowness perception" of Xee3. Xee2.1 has none of these preloading issues and when I go through files to move/delete them, it is just a lot faster (I deal with large 5Mb+ files from a camera so that preloading issue is really perceptible).
