The fillet command gives you a trim option that will either trim or not trim both selctions.
Yes, I know about that, but when doing wiring diagrams, I often want to trim one or the other... not both and not ...neither.
My ideal Fillet command would allow me to just be merrily filleting along with the ability to transparently enter "(B)oth, (F)irst, (S)econd" and another handy option would be to Fillet multiple lines to the first selection (with a fence) much like you can do with the Extend command. Seems to me that the "mUltiple" option should do this, but to be honest, I can't figure out what the heck it does!
