Okay but starting a lesson on Photoshop with the circle tool is like starting a lesson on Word with inserting a table. If working with abstract shapes is your modus operandi something like Illustrator or Inkscape makes a lot more sense as a tool.
Dude.... idk if I know if I've ever seen a more accurate simile than that. Equally "buggy*", frustrating, and absurd if you have little to no experience with it
*idr word tables well but I suspect it was like pen tool where it wasn't so much buggy as it's hard to make it work right if you don't get it yet
