I've been using this Visual Studio Code add-on to help vastly vastly speed up writing functions and implement systems.

For example, I could be in the middle of a function where I have a vector of ships and type:

//sort ships by their HP

and it'll generate the code to do it right there.

Or I could type in something like this:

tech_GreaterDiplomacy_Desc,

and it'll automatically fill in "A new technology for improving our relations with other civilizations."

I.e. it'll add flavor text that it generates.

I'm still in the beginning stages but this thread is a good start for anyone wanting to talk about it.
