It would be useful if the filament manager included a few additional fields for organization, such as a custom ID to help locate the corresponding filament swatch again, or the storage location to easily find the spool in a cabinet.
At the moment, this information can be stored in the notes field, but having it structured—so that it can also be sorted or filtered—would of course be much better.
Perhaps it would be helpful to allow users to define a few custom key-value pairs.
