"Ableton Live 10" introduced a great new feature called "Collections"
"Collections" appear in the "Live" Browser Window
"Collections" are useful because they allow for another level of organization personalized to the way you work. You can add files, presets, Audio Racks, Instrument & Drum Racks, devices, samples, sets, etc. (anything that can be displayed in "Live's" Browser Window).
There is a maximum of 7 "Collections", coded by the color that, can be renamed. (Currently, the colors are hardcoded and can not be changed).
You could create a "Collection" for Compressors or EQs, for Instruments or Sounds.
For example, I created a "Collection" for the Racks that I have made and those of third-party producers that I work with.
To add an item to a "Collection" Right Click on the item and select a color. The item will now appear in the "Collection" assigned to that color.
