// To allow seamless switching between custom titlebar and native os titlebar,
// I had to add most of the window creation code here to split both into seperete functions
// WHY? Because I can't use the same code for both due to annoying bug with value `frame` not responding to variables
// I'm sorry for this mess but I'm not sure how to fix it.
