Help center
Everything you need, organized by what kind of mess you're making.
The full help center lives inside FlexGrid. This is the online mirror: searchable, linkable, and mercifully free of chirpy mascot energy.
Getting started
Open the app, drop a folder, and you're already running. These are the three articles new users finish first.

Adding media
2 min · Cmd+ODrop, add, replace, or append. FlexGrid merges multiple folders into one pool and remembers the recents.
