// @description Adds new column with public score to the animelist
// ==/UserScript==
/* Version 2 - Changes
1. Public score column is only added and populated when the large table header is being clicked, e.g. "Plan to Watch"
2. Public score is being cached locally to reduce number of requests
3. Public score can be completely refreshed by clicking the large table header again, when the column "Public score" is already visible
4. All top 500 public scores will always be loaded with 10 requests
Version 3 - Changes
1. Add context menu entries instead of relying on large header table being visible
Version 4 - Changes
1. Add context menu entry for manually enabling the script instead of always load public scores. Scores are loaded automatically until the menu entry is used
Version 5 - Changes
1. Bugfix for manual activiation toggling
