i was trying to use a dbus script to do that but i failed, you just need to enable “run all Konsole windows in a single process” on konsole, and put a shortcut on the “open a new tab” on system settings(you can even put the default ctrl+alt+t) it’s going to open a konsole new windows if nothing exists or open a new tab in the existing konsole window

I’ve tried that setup before and it works pretty well. Enabling “run all Konsole windows in a single process” definitely helps keep things tidy, and setting up the shortcut for opening a new tab makes it super convenient. I usually go with Ctrl+Alt+T since it’s just ingrained for me, but it’s nice to have the flexibility to either open a new window or a tab depending on the situation. It’s a solid way to streamline things without needing extra scripts.
In Konsole, the default to adding a New Tab is Ctrl+Shift+T. Users can also split screen with Ctrl+Shift+( and Ctrl+Alt+), which is just so useful.
You can launch konsole with as many tabs as you like ( --tabs-from-file). And, you can launch it in split, quarter…as well. As a matter of fact, you can launch it split AND running a predefined command in each split ( but I can’t find the d…n script anymore) Just add the options to the desktop application.
