Embarrassing question...Know it's an easy solution but I can't find in forums so...
In KDE, my minimized windows are not going to bottom panel. They are being minimized to middle of monitor and disappearing?

Like I said, embarrassing. Would appreciate any assistance in getting minimized windows back to bottom panel. Obviously I made a configuration change that caused this but I can't find where.
Thanks.
Add the Smooth Tasks widget from Add Widgets (may need to Unlock Widgets first)
Edit - another plasma widget that does the same is
plasma-applet-icontasks but this first needs to be installed using Synaptic
