Autohotkey Online Reader Autodownload Macro 2.2

; Simply install Autohotkey (https://autohotkey.com/download/), save this file as whatever.ahk, and double click.
; A macro for when there are no download links available; takes care of opening images in new tabs and downloading them.

; V2.2 Changelog: Put reused code in functions, added a double-check for trying to access save dialogue, added GUI instructions

; README
; A hacky AutoHotKey macro by meterion for idle downloading
; To use: Navigate to page 1 of desired gallery. Press Ctrl+q.
; Follow the prompt, leave computer alone as it does its thing (currently cannot function in background).
; Speed: ~1.5 minutes per 20 pages
; Press Ctrl+i for extra beeps lol (don't do this while it's running tho)
; NOTE: Makes an .ini file in the same directory it's used called "autosaversettings.ini"
