Hi, I've made a webapp to help me organize guitar chords, and made it available for anyone to use here: Chord Commander

It has user defined grips, and chords, and automatically matches them together and groups them in a multi-row fretboard layout that gives a nice overview. It supports rootless voicings, symmetrical chords and chord homonyms. Comes with a default collection but is editable by the user. Loads/saves the collection via a local json file.

For the technically inclined, the source code is available here: joexo/chord-commander: A guitar chord voicing tool that loads faster than you can tune your guitar. - Codeberg.org

Maybe you'll also find it useful.
