Please consider what is most important before asking for features already solved in appropriate tools.
I understand why people would like Lightburn to eliminate the need for things like Inkscape, Corel Draw, Illustrator etc.
All tools have a purpose, many can be misued/abused for other tasks, not ideal.
Lightburn should be a Laser first tool, other conveniences like drawing capability should rank low.
Adding feature to make the operation of a laser machine easier. RDWorks is incredibly powerful and has a number of features that have yet to be ported over, these should be prioritized and possibly even improved upon.
Inkscape on Windows is quite a decent piece of software, and free.
Affinity Designer is cheap and excellent for Mac.
These tools allow for so much more capability designing the things you need. Right tool for the right job.
