Bundles should hold 64 of any item

As of the most current version, bundles hold exactly 1 stack worth of items. This is great if you have a lot of items in your inventory that aren't fully stacked. However it still doesn't solve the issue of non-stackable items (like tools & armor) as well as items with smaller stacks (ender pearls & eggs) taking up a lot of space. What if didn't matter, what type of item you put into the bundle?ß, as long as it doesn't exceed 64?
