System Monitor: Display individual threads and thread names in process list / process tree view

Feature request:

Currently, System Monitor can only display processes and the number of threads per process. It cannot display individual threads and their custom thread names like e.g. htop can.

It would be fantastic if the System Monitor Processes panel could have a Processes/Threads toggle, and display custom thread names by default when display mode is toggled to “Threads”.

The toggle state would be persisted, just like the tree vs list mode state.

Example of htop showing nheko’s custom thread names:
