I feel octoprint would gain if, in addition to the current handling, there was also an optional setting in config.yaml to set the default sort order for the files list.
Not unlike @Doprintityourself it feels like I have to click on that wrench and select Upload datum descending again and again. My cookies are usually on "delete when browser ends" and I suspected the setting died with that just like google search makes me click agree to something I'm opposed too again and again.
Local Storage should have a longer half life. Still, browsers storing data on user's machines - it is a war zone.With tracking and fingerprinting there are good reasons to clear browser data in short intervals.
On top of that it's not me and my browser, more like 5 different browsers on 2 or 3 boxes. Firefox, Waterfox, Chromium, brave, Opera, even Safari on the laptop. A browser window often represents a project and since I know of no way to name a window - it always picks the title of the current tab - I tend to use different browsers for different projects.
I don't want to bore you with my habbits, just telling this to point out that there are use cases where it makes sense to have server side settings for something like the sort order of files.
