Looks like a really useful tool. Can it be altered to search MZ projects as well? For the price, even if it can only search MV, I'd still consider my purchase well made. :)
All I had to do was drop in a copy of Game.rpgproject to override the check of being a valid RPG Maker MV project folder and it worked beautifully! This is a really cool program and certainly one that will make debugging so much easier. Thanks for sharing this, starlit. :
