I use Kanbanote (paid version). It has hiccups - right now it will not update if I have the note open in the Evernote desktop app.
BUT I REALLY LIKE IT. ( I also like Filterize - I pay that too).
Just buy the guy out already and make it work as an add-on.
I don't care if AI will clean up my notes, or if AI searches for me the searches I'm searching - we need a kanban system.
Then Evernote becomes a simple but very effective DIY CRM in addition to everything else it does
