I mean that I can save different versions with different settings of a pen , maybe give it a name or delete, so that I have for example a yellow green fineliner with small thickness, change it to a blue fat fineliner but saved the pen before so that I go to a pen library and select the old one. I don't have to pick the colour again and don't need to try to get the old thickness.
Oops, sorry you had fixed it in the new update!
