export to JSON
It would be most useful to be able to export some library or entry, formatted as a JSON.
That way, one might share the data more efficiently. CSV works fine if you are working with spreadsheets. Yet is a mess otherwise.
JSON bridges the db to fittable code for devs, is way more readable, allows direct parsing to/from SQL, is imported & exported straight forward on most online db servers...
I find most annoying working with a db and not being able to take the data (without a hard time manually reformatting) to whatever other app I am working the data with at a backend level. Thus meaning having to rewrite the data twice. That discourages from using this app in the very first place, whereas it has an impressive visual and editing flexibility otherwise.
