Recently, icons were added to the left side of every favorite in the Favorite's bar. Even if it can be useful for some users (as it shows what kind of favorite each favorite is), for other users it just takes a lot of space (reducing the number of favorites that can be inserted in the bar). So, the icons on the favorite's bar should be optional, so that users who need them can have them visible, but users who don't need them can hide them (in order to have the maximum space available to add many favorites).
