I don't think anyone does, tbh. It's a waste of time. I DO however name the track they're in, right click track and hit "auto name children".
If I have a drums track, this will name all of the unique patterns, as they appear in order, "Drums #1", "Drums #2", etc. When I right click the pattern selector number view (the tiny window next to the record button), it'll list all of my patterns by name, letting me choose the one I want, and even more useful, differentiate between patterns of different tracks/instruments.
