Adds clickable labels on lists with movie data (checks, runtime) and allows re-ordering lists without page reload. Sorting by multiple criteria sort of works, but is rather finicky to get right. Double-clicking empty space in a row hides it.
Supports the latest Firefox + Greasemonkey and Chrome (49+) + Tampermonkey.
How to use: open any movie list, mouse over the 'Filter' button (on the top near the tabs row) and click 'Load data'. The script loads labels only for movies that are on the currently opened tab.
Warning: the script can put a significant load on the ICM server when using it on large (500-1000 items) lists, so use it sparingly.
