Illustrator Lite Essential version, for 2D graphics only, without 3D
An "Illustrator Lite" that cuts out everything except the essential vector functions, and actually responds quickly, for crafters: no 3D, but with border feature etc. in order to work with digital cutters without expense
So it would be a entry level version of illustrator — concentrating on 2D output to SVG for electronic cutters, plotters and other crafting tools. Similar to Photoshop elements but for those needing to work with vector files.

Illustrator is just way too slow. If you just drag an item, it really needs to follow the mouse. Everything needs to be snappy. It's just way slower than it was in the old days. Don't tell me it's something to do with my system. It's just too slow. Make it as fast as Figma.
Perhaps a way to do this is just to have a version that removes a lot of the kruft, and is purely a vector-based program without a lot of the other features, such as bitmap manipulation, styles, etc.
