A few years ago I started writing a small utility for managing assigns, but never finished it. I finally got around to getting it to a more or less finished state and have released it into the wild. I don't know if it's something many other people would find useful; I use it occasionally, but if anyone else might find it useful, it's available
on my website and very shortly on Aminet. It's 68k/OS3 code using MUI, but works fine on OS4 and MorphOS too, and most likely on AROS 68k too though it's untested.
Screenshot here to give you an idea of what it does
