What this is

This is my personal tooling for videoconferencing on Ubuntu. It features Stream Deck to control OBS and some little shell functionality. It is built in Python and a reasonable amount of Bash.

It provides additional sinks, sources and connections in Pulse Audio to support monitored audio output to Teams.

It provides an AppIndicator for administration and user feedback:

Thanks to Lorna Jane Mitchell for inspiration. For me, Python was more approachable than Go.
