PUBLIC MARKS from decembre with tags source & userstyles

I see no documentation about this and I have few suggestions about it. I think this is a must-have feature for the freedom of users. A user should be able to install styles from other sources. Example: User goes to www.example.com User clicks on the link (www.example.com/name_of_the_style.user.css) Stylish detects the link by ".user.css" component Stylish shows a dialog: "Would you like to add this site to allowed domains list?" └► This dialog is only shown once and shown when it is required └► Domains can be removed/set/added from User Styles tab in about:addons User clicks "Yes" Stylish shows another dialog "Would you like to install this style?" User clicks "Yes" The style is installed.
