I have to say, I'm someone who doesn't really use all the graphics packs or whatnot, but generally speaking, I have a lot of custom init options I like.
For one, I can't play without using 5 and 0 as "up (z-axis)" and "down (z-axis)", respectively. The idea that the numpad is used for directional control in every direction but vertical, and those keys require repositioning your hand across the keyboard is just absurd in my mind.
I also have a personal custom tileset, a personal preference on things like the brightness of the colors, and a few other odd things that take messing with raws or init options to put in. Because I have to spend so much time messing with these things, I generally find it easier to put up with bugs than update my game version except every 4 versions or so.
I find the graphical interface you guys put on this to be very useful and intuitive and I commend you on it.
I would ask something, however, to maybe make it more useful to still lazy, but less newb players: Make some sort of way to import settings from a previous version of the game into the new version of the game, without having to just copy-paste the init files over, that the init files warn us not to do by just copy-pasting.
