For some reason I haven't been getting emails for this thread and I just checked to find some replies so I'm sorry about the absence!
I'm really happy that you're liking it, I'm really surprised that this is (as far as I'm aware) the first Touhou launcher, I've only been playing for about two months!
Shockdude, you'll be glad to hear that a few days ago I set the th folder and the fan folder to be created automatically if they don't exist and today I removed the splash screen (honestly, I never really liked it in the first place). Unfortunately, saving settings wasn't working when I first made this for some reason so I just kind of gave up, but I'll try again and include an option to close the program when a game has been launched. For now, though, I can add a checkbox although it'll have to be checked every time you run the program so it kind of defeats the point of saving time so I might not do that.
Again, thank you for liking it! I'm incredibly happy about how well this has been received by the community!
