Like a "reload titles from image metadata" link? Yeah, I could see that.
Times are hard to estimate, but let's see.. I'm graduating on the 21st... after that I'm working, but should be able to code nights and weekends sometimes, and I really want this metadata support in the 1.1 version (with sub-albums) so let's give it six to eight weeks, conservatively. I could be done a lot sooner if I find the time.
The technical stuff shouldn't be too hard... I'll mirror the file metadata in the database (much much faster) and probably use the mtime as a last-modified date to see if I need to reload it. And of course, if the database is ever corrupted, it will know to reload all metadata from the file again, just as if the file were new. Sounds pretty straightforward.
