Very cool project. I've been using this addon and can't live without it. Personally the best addon so far but it would be greater if the dev makes a cross-platform syncing feature as well.
Really cool and unique extension. My three suggestions would be:
1. An option to enable snapping to grid 2. Option to use a single middle click links to open in background tab for faster opening 3. Option for subfolders to be made like toggles so that they can expand/collapse.
