I use Sancho mods on a few games, and I appreciate the work he puts into it and what he brings to the table. The only things I can fault him on are that he will change hot key commands and, in the case of galleries, will use his own gallery set up even in games with a pre-existing gallery that only needs an activation bypass (Sunshine Love is where I've run into both of these issues). I haven't played this AVN yet, so I don't know if it has its own gallery; if not, then it's nice that he's adding one; if it does, it might be better if an unlock is simply programmed in. If he wants to do an "extra" like that mashup (what it looks like, at least), then have that be a separate thing.
Sometimes doing everything possible is just a little too much, particularly if it overwrites what everyone is accustomed to using, like hotkeys.
