I too frequently plug and unplug dock and external displays. It's a little painful to keep checking and sometimes re-add display source to get the default screen and voice recording working.

I wonder if the "modern" way for problems of this nature is to fork the open-source repo and ask your favourite agent to strip it down to bare essentials that you need (performance gains) and add the specific feature enhancements you want (needs to work only for your configuration -- may not pass the quality standard needed for a PR)
