Clarified differences between the settings, eg. options mode vs action mode for clicking the extension icon.
Added functions to easily delete the created bookmarks:
Double click function to remove them in action mode, and normal button for options mode.
Compacted the extension so it takes up less space, moved some of the options to dropdown menus only accesible when the setting in question is enabled.

Changed default hotkey to fix issue with certain locales where alt + s opens the MENU -> HISTORY selection.
Added text to let you know when a bookmark was successfully created / edited
Added options to truncate video title, enabled {time} parameter by default
