I use dual monitors and heavily use the expo compiz plugin (equivalent to kwin’s ‘desktop grid’). However, the behavior in KDE is a bit odd to me.
When I click virtual desktop  on the left monitor,  on the right monitor zooms with it. The behavior I’m used to in compiz would be to have both  on the left desktop zoom if I were to click .
Sure, this behavior “makes sense” knowing how KDE treats multiple monitors as separate activities but even after setting up matching desktop backgrounds on the monitors, I find it confusing to my workflow.
