For example, if I had tags: A, B, C, D, E, and F. Normally the tag filter would order them as such, however, if I had favourited the C and E tags, the order would now be C, E, A, B, D, F. Alternatively, the favourited tags could appear in the list twice; at the top and then again in their normal position, so using the previous example: C, E, A, B, C, D, E, F.
