I'd like to be able to assign descriptive names to work planes - this way I don't see a list of work planes and have to guess which is which.
Right now I am working on a project that I'd like to have a work plane representing building column lines. It would be great to be able to label the column lines by letter and number, as they are in the building. This would help me be able to pull dimensions off of the the column lines instead of the faces of the columns, since there aren't really convenient snap points on the column center lines.
I'm sure that this idea has other practical uses too.
The other thought would be allowing renaming of frame generator components so I can label the columns accordingly.
