Suggestion: Allow for multiple ways to sort categories. The default allows for alphabetical sorting, which is only helpful if you know the item names. In big clumps of similar items, allowing a tiered sorting system would be beneficial. Some examples discussed would be the ability to sort by ilvl, by slot, by rarity, by count (stacks?), or alphabetical. And -- allowing all of those filters to apply in a specific ordering.

For example, if you had 10 crafted helmets of the same name, you could sort them by rarity (mythic first, heroic second, etc) and then item level. Since they're all single items of the same name, slot, count and alphabetical wouldn't apply.

For one example of why this might be useful, I have a "teleports" category in Adibags and it puts all three Stormwind cloaks together. In Betterbags they're not all next to one another.
