When deciding which equipment to keep and which to sell I usually like to keep a light, a medium weight and a heavy each so later I have options when building my loadout. But currently it is impossible to sort equipment by weight so I constantly have to re-read all equipment types (armor, pants, gloves, etc) to check their weight while they are scattered around my inventory.
My best solution for this would be to actually allow you to apply multiple “sorts” simultaneously, for example, you could “sort by equipment type” then “sort by weight”, so first you would have all the armors sorted by weight, then all the pants sorted by weight, then all the gloves sorted by weight, etc.
This would make it IMMENSELY easier to work with my inventory!
I hope this change can be implemented and thank you very much for reading 
Agree and I think a filter would do the job for filtering items with/without a tag
Also we require a lock system for the items that we like so we don’t sell them accidentally since there is no buyback.
