You might want to update to 1TB drive.  They are not very expensive these days, there are plenty of options - simple look I would think you could find a 1TB ssd or even nvme somewhere between 50 and 100 bucks. when I have moved to larger ssds in laptop in the past, you can just connect the drive via usb - image.  Then take the old drive out, put in the new drive and there you go..  If your concerned about how much space you have left this prob your best bet..   

I see! Wasn’t aware of that. Even though they started off with desktop app for Mac before Windows. Should be on it’s way soon! 🤞

It's a Developer Beta 1 not even a Public or User Beta, I doubt any of the design is 100% finalized yet.

Was going to comment the same thing. It's SO annoying to have to go back to settings every time I install something new or some apps like discord update and the icon is hidden again.
