Thanks Xilmi!
I personally really like the break out in advanced options and controls between OXC, OXCE, and BOXCE specific settings.
I can more easily filter and identify the BRUTAL AI settings and what's dependent on them and what's not. It also lets me see what's provided between each, OXC, OXCE, and BOXCE.
Regarding identifying if there are key assignments that conflict. Sometimes I want the same key for two options and many times not. I've seen in some games the key combinations menu will highlight red or another color the key assigned when two hotkeys are assigned to the same key.
Something like this in OXCE to show conflicting assignments would be a nice touch. Where conflicts would be highlighted across oxc, oxce, and boxce, and for each section, i.e. both assignments in battlescape but not across sections like between battlescape and geoscape because that wouldn't be a conflict.
