Obligatory: Thank you for your terrific work on this free software.

Is your feature request related to a problem? Please describe.

The largest benefit I derive from this addon is a quick, at-a-glance view of how my vaults are looking on multiple alts. As such, I would like to be able to sort Mythic Keystone and Mythic Best way nearer to the top of the list, right after the "Raids" and "PvP" items in the General section of Quest Progress.

Ideally, I would be able to sort "Raids" "PvP" "Mythic Best" and "Mythic Keystone" as the very first four items, even above saved instances such as Amirdrassil and Aurostar. (and next expansion, remove PvP and add outdoor content when the vault changes).

If that is significantly harder or not something you wish to pursue, then at least having these 4 items be able to be sorted together, immediately after saved instances, would be a strong upgrade. I would suggest changing this to default behavior; I imagine that having the vault items plus the "what keystone do I have?" items sorted together by default would be an upgrade for most players.

Describe the solution you'd like

To fully tackle it, you could move "Raids" and "PvP" as well as "Mythic Best" and "Mythic Keystone" to a new "Vault Information" section of the General Settings tab. You could display these items below saved instances by default, with a a toggle for "Display Vault Information Above Saved Instances?". A cherry on top would be to have sorting options exactly like on the Characters pane, so users could sort the four fields and toggle visibility. Or, if you don't want to do that, I would suggest to always have Mythic Best 3rd and Mythic Keystone 4th, so the 3 vault fields are 1-3, and Mythic Keystone is grouped with Mythic Best.

If that sounds like too much or you don't like that design choice, then a most-of-the-way solution could be to move Mythic Keystone and Mythic Best from Miscellaneous Tracking to the General Tab of Quest Progress to allow for Sorting in the Sorting Tab of Quest Progress. Again, I would suggest having these 4 fields be sorted to the top by default. That wouldn't tackle the "I prefer them at the tippy top above even saved instances," but if that is an easier change I am all for it and would be delighted.

Another option I considered would be to change the functionality from "hold Alt to show all data" to "holt Alt to show more." Or add a "hold Ctrl to show more" if you want to keep the alt=everything view. I never want to see all 60+ fields for all 20 of my characters. But if I could see just the 4 lines I care most about on the 5 characters I care about most in the default view, and hold alt/ctrl to show 15 lines on 7 characters, that would be nifty. You would have to rework a lot of UI for this though, changing options from "On/Off" to "On/On-With-Alt/Off", so unless this idea really excites you, I don't Imagine you'd want to go through the UI effort on it. If you really like this idea, I am happy to resubmit it as a standalone (or you can if you want to) for another feature request. Just from my POV, grouping the 4 vault items would be a 9/10 priority, and changing the alt functionality would be a 3/10 priority (and again, my guess is that it would be a lot more work).

Describe alternatives you've considered
I've considered disabling everything except the 4 fields I most care about. Or, disabling everything between Raids/PvP and the Mythic Keystone features, so the 4 fields I want together are together.

However, this addon is a victim of its on excellence: I don't want to lose out on seeing progress on weekly quests and lockouts. I would like to have these four grouped (ideally as the first four items) and still be able to see everything else I want to see. I would like to have my cake and eat it too. Thank you for your consideration!
