my advice is keep the minimal amount vars installed to speed up. so the option "show only not installed"/"hide all installed" seem not needed.
there is an "sort by" option(New To Old Package) to view the newest downloaded vars.
The "sort by" option does not work as you describe it does.
If for example I were to download some random scene right now from the hub, it's "date" would be the date it was uploaded onto the hub, NOT the download date (today).
So if I download a scene that was posted on the HUB, a year ago, I have to first go trough several pages of other vars that are less then a year old..
The issue comes from, when a var is downloaded from the HUB, your scene browser does not see (Or even rewrite it's file creation date) it as a "newly downloaded file" But it only sees the original scene creation date, which can be months or years old.
I assume the intention is that it sorts files from new to old, by date it was added/detected by the scene browser.
But what it does in reality seemingly is that it only looks at the actual .var file modification date (The last time the .var was edited, which ussually is the date at which it was uploaded to the HUB as far as I know).
I could technically grab any random .Var that's currently at the END of the list if I were to "sort by" New to Old, and make a slight adjustment to the .var file, to then make it appear at the very top of the list.
^This is the behaviour I wish I could get automaticly when I download something from the HUB, that's all.
