Bundle UI should be expandable.

The current bundle UI is okay, except for one glaring issue: it hides its contents if there's more than 12 unique items, with the amount of hidden slots being indicated by a "+n" in the last slot. Having to take items out of a bundle in order to see the rest of its contents isn't intuitive, it isn't cohesive with the rest of the game's UI design, and overall, it's just tedious. I see two ways of going about fixing this:

Option 1: The "+n" should be selectable by scrolling over it and right clicking. This should expand the UI to show every item at once. If there's an issue with it being so big that it covers most of the screen, the empty space between each item slot could easily be reduced to make it more compact and consistent with every other container UI (kind of like how the bundle UI appeared in its second iteration, only now with the added scrolling capability and without the old white container slots).

Option 2: Right clicking on the "+n" could instead cycle through different "pages" of the bundle to keep the maximum view of 12 slots while still allowing the user to see all of its contents.

Extra Note: This isn't completely necessary, but it would be nice to have a number indicator (x/64) that shows how full the bundle is on top of the already existing capacity bar, so there's more precision and less guesswork.
