* # What is InstaMagnify?
*
* It's your portal to the highest-quality, largest versions of Instagram stories, albums, photos,
* videos and profile avatars!
*
* By default, Instagram only shows you low-quality media. But by installing this utility, you'll get the
* magical ability to easily _view_ or _download_ the largest and best looking versions of _any_ media!
*
* Liberation!
*
* But wait... _that's not all!_ You will _also_ discover that all profile pages (timelines) will be
* enhanced with a loading indicator in the bottom right corner of the window, which shows you how much
* of the media has been loaded by your scrolling so far, such as `"36 / 628 (5.7%)"`. You'll no longer
* have to keep wondering how much further you have to scroll to reach the end of the timeline! ;-)
*
* _And_ to make your life _even easier_, it will _automatically_ click the "Load more" button for you,
* so that you can effortlessly scroll and scroll and scroll and view and download media and... :-)
*
* Have fun and enjoy!
*
* # Features.
*
* - The most advanced code of all Instagram-related userscripts, written by the author of the
* largest 3rd party Instagram API library in the world.
* - View or download the highest-quality, largest versions of Instagram stories, albums,
* photos, videos and profile avatars.
* - Displays a timeline media scrolling progress indicator in the bottom right corner of all timelines.
* - Automatically clicks on all "Load more" buttons so that you can effortlessly scroll through media.
* - Automatically closes the annoying "Get the mobile app!" popup dialog which Instagram shows to some people.
* - Automatically closes the even more annoying "Sign up for Instagram!" bar which is shown whenever you aren't logged in.
* - Automatically closes the "Experience the best version of Instagram by getting the app" bar which is shown after logging in.
* - Supports protected (signed) media URLs, such as those used by stories.
* - Supports _all_ Instagram media types and media view-panels.
* - Your choice of convenient mouse and/or keyboard controls, whichever you prefer the most. :-)
*
* # Feel like thanking me for my hard work?
*
* Totally optional but _truly, deeply_ appreciated and brings a great smile to my face,
* and inspires me to keep working. ;-)

*
* # Instructions.
*
* Simply hold down a modifier key and click on any Instagram photo, video or profile avatar!
*
* - `Shift-click`: View in the same tab.
* - `Alt-click`: View in a new tab/window.
* - `Shift-Alt-click`: Direct download (only if your browser supports it).
*
* Alternatively, you can use the keyboard controls, which are definitely a lot more convenient
* if you're already using Instagram's own `left`/`right`-arrow navigation to switch between media!
*
* - `Shift-F`: View in the same tab.
* - `Alt-F`: View in a new tab/window.
* - `Shift-Alt-F`: Direct download (only if your browser supports it).
*
* If you ever forget the commands, simply hover your mouse cursor over the media loading indicator
* in the bottom right corner of each timeline, and you'll see a tooltip with all of these commands.
*
* Note that the "direct download" feature requires a browser which supports the modern HTML 5
* "download" tag, such as Google Chrome and Safari!
*
* You should also note that _your web browser's_ "how to open new windows"-preference controls
* whether the "View in a new tab/window" action will open a tab or a window. Browsers _don't_
* give scripts any control over that choice. Which means that you have to _change your browser
* settings_ if you want to specifically choose which window-type you're using.
*
* Lastly, it's worth noting that you can actually click on media directly on the timeline grid
* (not just on their media pages/media lightboxes). However, if you click via the timeline grid,
* you will _only_ be able to see the first image in case of albums or the thumbnail for videos,
* since the rest of the media details haven't been loaded when you haven't opened its media page.
* And you _may_ not get the highest-resolution media via this method (the best quality is only
* _guaranteed_ when you've clicked on the media to view it properly). But this ability to open media
* directly from the timeline is still a _great_ shortcut which is definitely worth knowing about.
* Have fun!
