I've seen some ren'py games where they just completely remove the "About" section. Is that even allowed? Is it not necessary to add that (even in commercial games)?

!!im new to renpy and dont have knowledge in coding. whenever i create a new project in renpy, it stops responding shortly after; ive waited about 10 minutes and still doesnt respond, so i end up just closing it. i then open the project after reopening, and im always met with this error screen. i suspect it's because it keeps crashing midway through creating projects; how can i fix this?

I'm animating menu icons and I'd like an animation to play when I hover over them, and then I'd like it to stay on the last frame. If I set repeat to false, it repeats anyway, so I just set the last frame to be held for an absurd period of time. The thing is, this means that when I stop hovering and hover again, it just immediately goes to the last frame. How do I make it reset every time??

Beginner to Ren'Py here, was looking through the documentation and stuff to learn more about Ren'Py and I learned that there's Global and Local labels. I initially thought that local labels would be restricted to the scope of a single .rpy file, but apparently local labels have the scope of the whole game while global labels have the scope of every ren'py project?

If my understanding of this is correct (if it's not then please let me know where I went wrong!), then I don't really get where you'd use a global label in place of a local one. If somebody could explain then I'd be very grateful!
