c2p Thank you for your answer here!
Jumpy This, too, is really great info!
Unfortunately, I had already been on the fence as to whether I wanted to go back to my beloved KDE Plasma, and though this (the size of the budgie clock applet) wasn't a contributing factor, I found myself really missing the workspaces concept of isolation in KDE Plasma and I took the plunge. I'm writing to you now from the KDE flavor of Solus, and so far, so good.
Still, thank you both for taking the time to reply here, and I wish I could select both your answers as the solution for future users.
I have not tested either method, but I'll select the first reply as the best answer in case someone else comes hunting for it.
Thanks again!
