I knew I was forgetting a super awesome program that no one should go without…
OBS (Open Broadcaster Studio) - Live-stream, screen capture to flv/mp4, multiple sources & overlaying video on video, records off the GPU so it has a very small footprint, Open Source.
There is fraps and some others too… but program makes them fairly irrelevant (I use fraps only for the FPS counter now) ;). Must have if you want to record tutorials, record some footage from UE4, or live stream!
Also, for coders:
Visual Studio 2013 Community - Basically the Pro edition with different terms (max 5 users per company, make less than $1million/year, no Enterprise dev) - Which means it’s perfect for small UE4 teams!
NotePad++ - Syntax highlighting, supports most languages, lightweight
For Audio:
LMMS - Audio production, sound generator, beats/baseline, synthesizer, & MIDI controller
And Misc:
GifCam - Quick and easy program for recording Gif images.
Model downloads:
Yobi3D Search Engine - A search engine for finding 3d models
I’ll keep looking for more
