Window Rules and Custom Shortcuts from KDE Plasma, just earlier today I binded Meta+Ctrl+k to start Konsole in the directory of my latest modified prototype, open a per directory script which e.g. opens a browser tab, opens Vim in the file to edit, positions those windows properly, here browser on left half, console on top right corner.
Window Rules with its window picker is very convenient to get conditions and properties to apply. Custom Shortcuts is just a list of shortcuts you can add to start anything from anywhere.
Also I added my own wiki as a KRunner Web search, so if I type Alt+Space then PIM keyword it searches directly to my PIM from the center of my screen, also from anywhere.





Offline Android device, e.g. video projector, with VLC on it that starts at boot. Content from a USB stick.
If I want something live, I plug my GrapheneOS phone on it with a USB-C to HDMI cable.
Basically keep the device as just a monitor.
