2 quick suggestions ..

1) Might it be possible to allow 2 STACKS & 1 ITEM in these disks ..you can carry a single item of the resource or processed item you are collecting or making ..but i'd be nice to know that you could if you needed to ..split the stack in the disk to transfer to Inventory .. currently if you make the mistake of putting all the stored resource into the disk, but its too much to transfer back to your inventory, you're stuck making a disk-ful of the same item until it overflows.

2) A Key-bindable LEVEL Flight ability .. if you use mouselook, unless there's a way I haven't found, its very difficult to get exactly back to level flight afterwards.

Neither very important ..just niceties .. if you have time to make them happen ..great ..if not we can live ..lol
