Hmm. I'm reconsidering the code completion options. I thought I had gone through it painfully and tried to configure it how I'd like (without success) already. On a second investigation, it seems more promising. The code completion toolbar does exactly what I was requesting initially. I never noticed that. Whoops
Let's see about what seemed to eternally and ingracefully replace whatever I was typing, because that doesn't seem like such a solid complaint ( I was probably just being a dumbass ).
I was probably in a shitty mood and things didn't work exactly as I expected, so I didn't bother enough with actually coming to understand how it worked.
I'm often in a shitty mood.
All of this was decided when I first began to use Code::Blocks, which remains by far the best and most sensible C++ IDE yet. That was many years ago, so I've forgotten what code completion was like anyway. That was also with a much older version.
Edit:
No. Wait, it only adapts to the current scope. It's still a pointless browsing thing. Ugh. Also, I noticed the tooltip a few minutes ago. Yeah. I've made some comments about that elsehwere.
