The dock no longer shows the overlay with digits corresponding to shortcuts to launch apps (with <super>). It stopped appearing after I upgraded to Eoan.
The numbers are show neither with <super>q nor by holding <super>. Unlike #1846718, no overlay appears when hitting <super>+0 either (or some other number), although the corresponding item is launched/focused.
I have tried changing a number of things in org.gnome.shell.extensions.dash-to-dock, including setting hot-keys to false, as advised [here](https://askubuntu.com/questions/1082772/keyboard-shortcut-for-launching-application-from-dock-in-ubuntu-18). Alas, I couldn't make it work.
Not sure if it matters, but this is the second upgrade (install was on Cosmic originally). Here is the output of some commands that may be relevant:
