I got the menu icon back (Kickoff Application Launcher), eventually, but
I've now got a new problem. I'm on Slack 13.0 x86_64.
In the past I set an option using "Task Manager Setting" so that only
tasks from the current desktop were shown in the taskbar at the bottom.
Now the "Task Manager Setting" has vanished. I used to start it by right
clicking the task bar at the bottom and selecting it from the resulting
popup. But since I replaced the Kickoff Application Launcher icon the
"Task Manager Setting" has vanished. (Or maybe a long time ago - I only
ever set it once when I installed Slack 13.0 many moons ago).
Anybody any ideas how to get it back?
I've already tried the Task Manager widget and also deleted my
and rebooted forcing a new default plasma-appletsrc but all to no avail.
