Yes, I have found 1.23.5 one of the most efficient and the most fun viewer of the lot
And with it, I can add half a dozen specialized HUDs, without worrying about resources.
(Oh, I have to worry about AOs and contentions, but that's only normal.)
So, it is a shame that the 2.x version was not HUD add-on oriented.
(You know, have a special Add-on window or drop-down for just viewer options, mods, etc.)
To me, that scalar resizing of the screen to open the Inventory panel was not needed.
And we probably could have lived without excessive master folders for what we are wearing.
Usually, Change is Good but some changes are simply wasteful and destructive?
(I watched There.com hanging onto a new viewer like it would solve membership and other core problems, but it didn't.)
