Mentor suggestion

[Ed Venture]

I agree. Sometimes I go into space as a ghost to mute non-important station sounds and alt-tab to watch YouTube videos while waiting for round-end. I wouldn't mind a toggleable mentorhelp sound, as it only takes a second to tab back in and answer one most of the time.

Have you considered just being in the relevant IRC/Discord channel?

This may have what you want as you can set discord to make a sound whenever there is a new post. You can also set it so only mentor chat makes this sound. Mentor chat also shows mentorhelps.
