The one downside to this - depending on the speed of one’s cmputer - is the more draftblocks and pieces you add, the slower the application may start running. What most users don’t realize is that everytime you do something that causes the pattern to parse - such as adding a new too or changing an existing one - the app has to parse and recreate the pattern all over again. This is due to the parametric nature or the use of formulas in the pattern. The more tools & pieces, the longer it takes to parse.
