It would be nice to be able to have a tag functionality like in confluence , Wordpress etc.. where you can associate one or more tags with objects to describe attributes that can be used to quickly search for.
Although I understand there are 'custom fields'. They don't seem to be great for this type of task (although perfectly fine for other types of uses).
As an example.. using tags for location, or to describe hardware like GPU, or brand would make it so much easier to search for groups of objects nested in different folders and across different documents would be very very power and handy.
Also this would also be useful to create multiple flexible non hierarchical groups that don't necessarily have any direct traditional correlation with each other except how they are grouped by tag.
