Aside from the weekly world bosses and seals, there could be [a tab?] to keep track of profession related cool downs and which characters need to complete them, and another for custom tasks/goals. Perhaps the latter could even have an experiation date of some sort.
And maybe extend this as a separate section to daily / near-daily tasks?
This may already be an option:
Allow hiding of characters in the list. i.e. option to only show realm (group) chars, only show realm (group) of current faction, possible to deselect specific characters and have a [-]Hidden Characters list collapsed.
