there is a widget that lets you switch between virtual desktop. the good thing is that its easy to use. the bad thing is that it uses really much space in you panel if you have many virtual desktops. on windows there is also such a widget on you bar. here it is an icon, you can click on and it will show you all your virtual desktops. so my idea is that it will be possible on linux too to run this widget as "icon", when you click on it it will show you all your desktops Reproducible: Always Steps to Reproduce: 1. set desktop switcher plasmoid into you plasma bar 2. set to have 5 virtual desktop Actual Results: it takes much space .... Expected Results: it should be possible to have only an icon that shows the desktop only on click.
in other words a icon/desktop widget that runs qdbus org.kde.kglobalaccel /component/kwin org.kde.kglobalaccel.Component.invokeShortcut ShowDesktopGrid on click
It seems like you want Zren's Present Windows Button: https://store.kde.org/p/1181039/
Yep. I'd recommend just using that.
