Hello everyone! I am working on a Script and would like to know if it is possible to add some kind of loading screen functionality. My script manipulates large files and it takes a few seconds to see the changes after running it. Is there any way I can add in a loading screen that terminates when the script has completed running? That way the user has a clearer picture of when the script actually finished executing. Any help would be greatly appreciated, thanks a bunch!
