I’ll let the discussion continue…
But for the record I’m assuming SketchUp licensing will remain unchanged for the foreseeable future. I have examined all my computers and removed Make from all of them. I’m leaving Make installed on a Mac that I use only for testing extension compatibility (hardly ever). I’m purchasing one more Pro license for one user that really was using Make.
For my extension, future versions will work only on Pro (except for trial demo). If users want any updates they will be forced to purchase Pro.
