I think the most basic function missing is a line tool with dimensional constraints. You have primitive shapes, but using them effectively requires a line tool. Even being an educator and user of CAD, I tend to use Easel with 90% of my designs, however not having a line tool does make it more challenging at times. I will sometimes use Lightburn to design, then port over to finish, but please DO NOT go the route they did, it’s still inadequate. I would suggest a line tool similar to OnShape or Autocad Inventor.
