ReillyBrogan Delete ~/.config/bluedevilglobalrc and reboot
Thanks - that fixed it. I'm still hoping for some help with the "dock." Replacing the missing solitaire icon seems to have survived a reboot, so it's possible that I accidentally removed it myself. But this is how the dock looks after I click on the colored dot that represent Spectacle (so I could take the screenshot).
After I took the screenshot, it went back to 12 colored dots representing the icons. And after I clicked to "Enter edit mode," all back to normal.
