I think adding a note feature would be super beneficial to some users. For example, I engrave cutting boards then fill them with epoxy. It would be awesome to have a spot to enter notes on projects with the amount of epoxy used, amount of powders and things like that.
Also I do a lot of circular cutting boards and would love to be able to use a circle template to work off of in Easel vs the standard square/rectangle. It would defiantly make my projects a little bit more easier.
