Great work, I like this a lot. Some feedback: - It would be great to have the options of having tabs so that I could group my notes into a Math specific tab, or raw notes, code, etc. - Another option to the above tabs would be to sort the blocks by type (grouping all the Math at the top for example). - Having the ability to then save each block into a separate file.
