Hi,
I'm designing SQL Query Console, thoughts below 
need suggestions.

1. Console goes buttom of body, just like this:
内嵌图片 1
Is this design in a appropriate size? Or cover the lower part 
of
Navigation(I don't think)?
Scroll bar which close right screen edge will confuse users,
it's a page scroll bar, looks like a part of Console but doesn't
scroll Console. Is that doesn't matter?
Console is invisible at start, a button at top menu(or nav-panel?
I don't think) and a key shortcut can toggle it.

2. Console will use Code Mirror for make console basic, reference
Chrome dev-tools JS console. For browsers lt IE 8, Console will be
disabled(beacuse of Code Mirror).
Colors we using, for color blind users, such as Chrome did:
内嵌图片 2
Should I find other colors instead for warnings and errors, or only
use black?

3.
Commits will push to [my branch], merge al last, is that OK?

Thanks and regards!
