I have recently found the need for something that the Content Browser doesn’t seem to have implemented: Custom Filters.
I am currently working with many assets that all have specific visual themes [depending on which area they are being used in], and it would be a great if I were able to create my own custom filters such as “Furniture”, “Kitchen”, “Tools”, etc, and then be able to apply those filters to any asset desired. Also, the ability to put these into our own categories might also be nice. This would be purely for the sake of organization and easier asset management.
Just thought I’d share my input, as this is something that I feel would help with organization and quickly finding the correct assets.
