Difficult to distinguish process signals
The process context menu has four signal options: "Stop", "Continue", "End", "Kill". Even as a quite experienced Linux user it was not immediately clear to me which signals these options would send to the processs.
Some of these names seem to correspond to signal names. "Stop" for example corresponds to SIGSTOP. Others don't (there is no SIGEND). This created confusion for me as I didn't know if I had to select "Stop" or "End" to send SIGTERM to the process.
Translations make this even more difficult, as those words don't line up with signal names at all. (they can't, because those names are English only)
I would propose renaming the options "Pause", "Continue", "Terminate", "Kill". Furthermore the confirmation dialog should probably state the exact signal name that is about to be sent to the process (like SIGTERM).
