Why is the fix command even included? I'm just not going to use it, it's basically cheating. Actually, a lot of these commands are cheating.
The alternative is to rest, cast all your cure light wounds spells, rest again (reselecting CLW manually every time), cast all your CLWs, rinse and repeat. It's bloody annoying, and there's a reason SSI automated the process after the first game. You'd better hope for good rolls on your CLWs too, because healing a 40 hp fighter 1 hp at a time is not fun. You can use GBC's Fix if you're in an area free of random encounters, but otherwise yeah, it's cheating.
As for the rest of the stuff, GBC was made for GB veterans by GB veterans, and is sort og an all-in-one tool for surface level messing about with the engine, in addition to QoL features. Apart from that, it's a mod, period. That should suffice for an explanation.
I think it's worth for the hud (status effects, xp meter etc) alone. As for the "fix"-command: Yes, it's cheating. In PoR I used it only in the civilized area. In CotAB an onward I used the native fix-command. Not to forget you could rest spam in these games anyway.
