With a lot of AE2, you are able to simply drag items (or fluids) from JEI into importers, exporters, etc.

It seems you are unable to do the same with the ME Requester or the ME Requester Terminal from the ME Requester mod. When I do start dragging something from JEI, the slots in the ME Requesters/Terminal does highlight green, like it's a slot you are able to drag do. But, won't accept whatever I'm dragging in.

Pretty easy to workaround if it's an item, as I can just grab the item. But, if I wanted to make requests for a fluid it does not work as using a fluid bucket would literally want to craft buckets of said fluid instead.

I found a workaround for the fluids, if you have a bucket (or tank) of a fluid, you can shift+right click with the it to set the only the fluid state, similar to how you dump the bucket/tank into an ME terminal to store it into a fluid cell.
