So I read this and this and solved my problem. Basically I bind /temp/download to /media/$USER/download and then I can set the download directory in Chromium and Firefox snaps to /media/$USER/download and my downloads go where I want them. This was actually harder to figure out than it should have been.
Today I came across some tech writing courses available from Google: Overview of technical writing courses.
Note to self: I had a problem with the GUI on my Kubuntu VM not working under VirtualBox on a Kubutnu host. I fixed the problem by changing the Graphics Controller on the VM from VBoxSVGA to VMSVGA. I have no idea what the difference is, except that the latter works and the former doesn’t!
