They may have been asking for it for years, but I had a countervailing reason not to implement it - if you can cheat your way into unlocking the whole gallery, people will be more inclined to do that than to unlock it through playing the game, which is the preferred outcome. But it was taking up a lot of this thread, and your tool only made it worse, because then people were asking how to use the tool. So I made the hard decision to include it, even though it went against the design, so that people would stop asking about full saves (for the gallery, anyway - if people want full saves to make exploring the game easier, I'm fine with that).
The fact that it took no time at all to implement should suggest to that, perhaps, I wasn't not implementing it out of laziness or a failure of vision, but because I did not want it implemented, and implementing it was a compromise I made in response to feedback from the player base - to, among other things, improve the quality of this thread.
As I've stated before, we're happy to keep working on ToA as long as people want us to, but we also want people to play a complete game start to finish, even as we add new things, which is why we're planning to finish up Adventure mode this year and Story Mode next year. And we'd also like to open up new projects, even if we keep supporting ToA, because we have other ideas we'd like to explore (for instance, characters in a modern setting for dating/romance).
The only thing I hate about working on ToA is this kind of vitriolic raspberry-blowing from, usually, people who have a chip on their shoulder because we slighted them somehow, which is why I don't normally engage with it.
