This is pretty sweet but the UI does leave some to be desired. It would be awesome to have a UI similarish to onenote or a few others where on the left side you have a list of your boards, then either on the left or right side (users pick) you have a list of items in the board, then the rest of the screen is whatever the item is.
It is a really nice start and has a lot of potential but without a web version it just wont replace anything I use right now since you dont seem to support any of the BSDs and I do a lot of switching between Windows Linux and OpenBSD
