Description
Is your feature request related to a problem? Please describe.
Currently, we can only kill the process (i.e. sending SIGKILL).
Describe the solution you'd like
It would be helpful if we could send other signals, such as SIGHUP, SIGTERM.
Describe alternatives you've considered
Perhaps adding an action to send a specific signal to the process.
Additional context
In htop, a user can send a signal by pressing k.
