If remnote can do it you can too (skip to 01:50)
Probably the biggest painpoint for me with Marginnote at present is the lack of a decent Spaced Repetition System. This leaves exporting to Anki as the only option, but the Anki export never completely does what I want it to do. Even if it did, amendments are impossible. If I need to fix a cloze I have to do it again in MN and re-export. Not a realistic workflow.
The logical step then is to handle this within the application.
