#ifdef CUSTOM_FRONTEND_OPTIONS
#include "Frontend.h"
// Warning:
// All of the code relies on that you won't use more then NUM_MENUROWS(18) options on one page.
// Also congrats if you can make 18 options visible at once.
// About texts:
// All text parameters accept wchar(including hardcoded wchar* and TheText.Get)
// except FrontendScreenAdd(it's char[8] GXT key by the design of Frontend).
// All texts reload if custom options reloaded too, which includes language changes and via live reload feature in debug menu!
// Execute direction:
// All of the calls below eventually manipulate the aScreens array, so keep in mind to add/replace options in order,
// i.e. don't set cursor to 8 first and then 3.
// Live reload:
// You can add/change/undo the new options in-game if you use VS. Change what you want, build the changed bits via "Edit and Continue",
// and hit the "Reload custom frontend options" from debug menu. Or call CustomFrontendOptionsPopulate() from somewhere else.
// -- Option types
//
// Static/select: You allocate the variable, pass it to function and game sets it from user input among the strings given to function,
// then you can handle ChangeFunc(only called on enter if onlyApplyOnEnter set, or set immediately)
// and ReturnPrevPageFunc optionally. You can store the option in an INI file if you pass the key(as a char array) to corresponding parameter.
//
// Dynamic: Passing variable to function is only needed if you want to store it, otherwise you should do
// all the operations with ButtonPressFunc, this includes allocating the variable.
// Left-side text is passed while creating and static, but ofc right-side text is dynamic -
// you should return it in DrawFunc, which is called on every draw. ReturnPrevPageFunc is also here if needed.
//
// Redirect: Redirection to another screen. selectedOption parameter is the highlighted option user will see after the redirection.
//
// Built-in action: As the name suggests, any action that game has built-in. But as an extra you can set the option text,
// and can be informed on button press/focus loss via buttonPressFunc. ReturnPrevPageFunc is also here.
