brent Plank and XFCE seem a good fit.
Today I found out a neat function of Plank by accident. I was intending to increase the size of the text in Terminology on a Budgie VM using CTRL+(mousewheel), but my mouse pointer happened to be on the Plank at the bottom of that screen. Instead of the terminal text becoming larger, the Plank and its launcher icons did. So I scrolled up and down a bit, and the Plank enlarged and shrunk accordingly.
I moved the mouse pointer away from the Plank, and I was once more able to adjust Terminology's font size.
