Awhile back, I did some testing of Drawing app’s - my goal is/was to avoid Inkscape and find a robust app with simple user interface. The best two (IMO) are Boxy and Gravit. By far, Boxy is much cleaner.
Boxy is for Mac and Linux. Gravit is also excellent. Both have some minor ‘issues’ but are quickly improving.
I’ve had some recent interaction with the designer of Boxy and an export for Fritzing is on their “Todo” list
