Additional filter conditions and types

Not sure if this has been suggested before or if this is totally bonkers, but I think it would be neat to have filter conditions that link back to information about my character or items in my inventory (including stash and carried inventory). Perhaps conditions like:
1.) character level
2.) character stats
3.) currency quantity/types in inventory
4.) characteristics of items in inventory

Most loot filters rely on item level for handling progression show/hide conditions, and the above additions would provide a lot of possibilities for better tailoring filters for progression. Filtering against characteristics of stash items would also be helpful for quickly identifying drops that would be "upgrades" to existing equipment.

Additionally it would be cool to apply auto-filtering to vendor inventories, perhaps in a similar fashion as loot filters are applied to drops. This would cut down on time required to sift through vendor items while hunting for good stuff.
