Hi! Wanted to tell you thanks, I think this is a great plug-in and I appreciate your help when I was having trouble before (around the time you released version 0.11). No more problems, and the changes since have all been great.
I have a question about the one feature that would make this absolutely beyond perfect for my needs: a way to find media by tags/categories in the Add Media pop-up when I'm doing a new post. I'm guessing it's at least possible, since something along these lines exists in http://wordpress.org/extend/plugins/media-tags/ - but that hasn't been updated in forever and isn't, overall, as good as MLA for me anyway. My site has a new image coming up every three hours, 24/7, out of a large user-submitted pool that's living on my hard drive, and I try to have them lined up in advance. Right now, I upload a day's worth, put the appropriate credits in the captions, and schedule them, then go on to the next day's. Being able to upload and credit/caption them as they come in, then using tags/categories to find them when I'm doing the posts, would make it simpler - and would also make it easier for me to give a couple of other people the ability to do it if life happens and I can't. If you want to see it, site is http://cheezland.org
If it's not feasible, or not a direction you're planning to go, or whatever, no big deal. I figured it can't hurt to ask.
