First.. Thank you so much for making this! Made my life a lot easier :)
If I may come with some small requests, I would love to have a little more options..
- Sorting by (type, size, name, etc)
- Predefined filter (type, method, size, name, etc)
- Direct link to media?
I have a few more, but this is what I wish the most for.. Again, thank you very much for your time making this addon possible!
