@Steve arrays were the very first thing that came to my mind when I read “repeating commands,” then you went on to say it. 
I do a lot of designs of motorcycle hubs, so spoke holes and their respective features get to be very tedious.
So I agree, a simple “repeat” function would speed up a lot of things in my workflow.
@Yepher I also do multiple file type exports at once, and being able to batch the process would be nice.
Maybe being able to select multiple export file types on the main export screen, then a continue button, instead of one at a time. You can set the export settings for each type in the main app settings, so you don’t have to specify them every time. Kinda like setting default, but you can change them if needed during export.
Just an idea. I like automation.
