User:T. Canens/standard revision gadget notes


 * Doesn't seem to handle marks in headings - e.g., deduction guides (though that kind of abuses the heading mechanism).
 * Also misses markers in navigation bar headings - ex., Template:cpp/utility/navbar content
 * (Quasi-)empty section handling is inconsistent - hides in navbar content but not main text
 * "future" deprecation/removal should probably still show. E.g., "removed in C++17" should probably still show in C++03/11?
 * Hide/gray out inapplicable revisions. E.g., C++98/03 on std.
 * Should hiding not apply to "see also"?
 * Doesn't work on main page...
 * Examples can use later revisions :(
 * Need to somehow associate parameter descriptions with overloads so that they can be hidden
 * Navbar content may need reflowing
