Most popular mods - what do *you* use?

[JScones]

This is a variation on the popular "what mods should I get" question. However, I am not asking this question because I don't know how to use the search function, I'm asking so that the downloads section of Subsim.com can be updated (if necessary).

So, excluding Grey Wolves, RUb, IUB and NYGM, what mods do you use (please include the filenames and where you got them from)? No arguments, no flames, just pure "I use ... available at ...". And please be specific. It will allow me to see what the most popular additions are.

Consider this a fact finding mission.
