I had a suggestion for the Autoblog plugin. I ran into this situation with a project, and so I thought others might run into it too.
The issue is that I want to eventually pull in hundreds and maybe even thousands of feeds and GIVE EACH its own category. (Actually, I'd like to put each in its own child category.)
I am wondering what will happen when I attempt to add a feed to a category, and I have thousands of categories. It seems that the pull down list will get very cumbersome. So here's what I was thinking:
The current system seems to work fine for many (probably most cases), and so it would probably make sense to keep it. But then, if needed, maybe there could be a another section for this more involved situation.
Would it be possible to have a second section (maybe make it an addon) with a pull-down list of only top-level parent categories that could be selected as the parent category, and then have a text box where a new child category could be written in and created on the spot as a category/child category.
In this way, someone could easily select a parent category (of which there would be a lot fewer - maybe 20 or 30) and then create the child category there on the spot. This would seem to avoid the long, cumbersome pull-down menu.
Not sure how difficult something like this would be, but as it would solve a current problem I'm foreseeing, I thought I'd throw it out there.
p.s. By the way, would anything malfunction if a pull-down list got up into the thousands?
