Haven't even played the latest yet, just downloaded it and I always go to the Techroom first.
A Category for Ships and Galaxy Node Map with clickable items that gives you info about the system. THANK GOD.
Spent hours just reading everything.
Only gripe so far and maybe this is an FSO thing is I wish there was a way to make the font bigger in the techroom, like a + - zoom kinda thing but that's just me. Having a separate window is super helpful but the font is still pretty tiny for me but that's neither here nor there.
There's a Font Size Multiplyer in the Options screen. So awesome!
