I really like the suggestion about "migrating old stuff into dendron". This could probably be further elaborated depending on where people are coming from.
As for all the questions you've mentioned - I think I'm going to answer them and then put it up on our FAQ!
And thanks, I've been trying to document everything as I go along but I inevitably miss stuff. This is especially true as I've been using this style of note taking for so long that I end up taking a lot of things for granted
thanks for taking the time to leave feedback and giving dendron a chance 🙂
