I'd love the ability for the backpacks to be able to pull items from inventories directly into the backpack and then perform operations on them. So for instance, my mob farm generates a lot of Rotten Flesh and Arrows that I don't want. With this mod installed on the backpack and a Void Filter, I'd be able to somehow automatically clear out the target inventory and delete all the Rotten Flesh and Arrows.

Thanks for the mod! It's awesome!

Add Quick Withdraw Upgrade

Interesting.

I definitely have a quick-insert (opposite of quick deposit) in mind, where you click on an inventory to move items into it. The ability to perform actions on them as well should be doable, but may get a bit tricky.

I'd like to second this suggestion. I'm trying to use a backpack to automatically grab compressed dirt and decompress it, and then feed it into my inventory. As of right now I have to take it out of the inventory it's in, drop it on the ground, and pick it back up again. It would be nice to streamline it!

I'm also running into another problem with it, but I'll go put that in another feature request.
