While I understand that you want to make MC look and work a bit like iTunes, you are making it a bit hard on yourself.
For example, you seem to have deleted the default Artists View already, and you are editing the default Album View. It is much better to copy the default Views and edit the copies. Then you can go back and look at the default Views, how they are defined, and copy them again if required, to create even more Views. When you are all done you can then delete the default Views, if you still want to.
You could Reset the Views to defaults to get them back, but then you would lose all the changes you have made. So if you want to see what the default Views used now, the easiest way is to create a new empty Library (make sure MC doesn't try to automatically import everything when you do this. See the message in the Action Window, bottom left corner, with countdown, and stop it), then you can just switch to that Library any time you want to check the default View definitions. Or you can save the Default Views from the empty Libary and load them into your main Library. I keep just such a "Reference" Library to check what was in the default Library, although a lot of settings would be shared between the two Libraries.
Using the [Mix Album] field in the sort was a great idea w_axlrose1. That works in the top Pane of the Album View just fine, but it can break up the Artist grouping in the top Pane created by sorting by [Album Artist (auto)]. For example, I have three Albums by "Pendulum" in my test Library. Two are mix Albums. The non-mix Album sorts alphabetically amongst other non-mix Albums up the top, but the two mix Albums sort down near the bottom with the other mix Albums. The mix Albums are sorted at the bottom alphabetically amongst themselves, even though the mix Albums have the [Album Artist] set to "Pendulum", and hence the [Album Artist (auto)] is set to "Pendulum".
Personally, I just got used to Albums with [Album Artist (auto)] set to (Multiple Artists) being sorted to the top, so that all Albums belonging to one [Album Artist] are grouped together. If you wanted to move just the Albums that have their [Album Artist (auto)] set to (Multiple Artists) to the bottom of the list, and not other Albums that are mixes, then a custom field based on an expression would be required. Not difficult, just: IsEqual([Album Artist (auto)],/(Multiple Artists/),0)
I created a field called [MoveMultipleArtists], made it a String field that can't be edited, and made it a Calculated field using the expression IsEqual([Album Artist (auto)],/(Multiple Artists/),0). Then I sorted the Album View by;
[MoveMultipleArtists] (a-z)
[Album Artist (auto)] (a-z)
[Album] (a-z)
Done. With that setup all three of my Pendulum Albums stay together, and all (Multiple Artists) Albums move to the bottom of the list. I might even start using that View sometimes.
PS: Use [Album Artist (auto)] is View definitions, expressions and so on, not just [Artist], unless you only ever have one Artist defined per Album. Which based on that image, you don't. Read:

PPS: sjames_chimera, have you worked out there is a bottom Pane to the Album View yet, which shows the file details based on the selection in the top pane? Have you checked out the "List Style" settings for a View? The default Artists View can actually work quite well with a List Style of "Thumbnails" in the top Pane, and a List Style of "Album Thumbnails" in the bottom Pane, if you don't need to see the Track details. That's why its good to have multiple Views, such as one Artist View that shows Track details, and one that just shows Albums, in the bottom Pane.
