What are your common frustrations with the OpenFF toolkit?

Hi, I’m Jeff, the current main developer for the OpenFF Toolkit.

There are lots of little usage problems that can’t easily become issues on the issue tracker, but that I kinda suspect that users run into. Stuff like “oh, I got this error message for a long time and had trouble figuring out that it meant the input was supposed to have units” or “the conda installs are too darn large”. This is a thread to vent about the small stuff, and seeing this will really help us developers improve the software (or at least the error messages!)
