With all the work from home going on, I recently discovered Visual Studio Code Live Share which has been pretty awesome for pair programming and pair debugging. It even has built in text and voice chat. Terminals can be read only or read/write by people sharing, I can browse their workspace and folders and it knows to attribute the author of a commit to a remote editor.

We were initially very excited about it and while we don't use it as much as we did, to me its essential for doing remote collaboration / pair stuff.
