Local Database Favorites

DEVONthink’s sidebar allows you to keep your favorite databases always at hand. If you want to have something similar inside a database you can easily set it up yourself like this:

1. Make a group named e.g. Favorites; maybe add a label so that it better stands out.
2. Now replicate groups that you want to make a favorite into Favorites.
3. Double-click a favorite and it opens in a separate window.

Alternatively you can use tags:

1. Tag your favorites, e.g., with Favorite.
2. Make a smart group that shows you just groups and documents tagged with Favorite.
