This addon modifies the Mission Journal to have two new entries in the dropdown: Available Missions and Tracked Missions.
Available Missions: As you roam through the world, nearby missions that you have not yet completed will automatically be added to this section so that you will not forget to complete them. They will be removed once they are completed. Please be aware that this will include hidden missions such as seasonal or faction missions that are currently unavailable. However, these hidden missions will not be expandable, so you will not be able to peek at the details.
Tracked Missions: Simply click the new "eye" icon on any completed, repeatable mission to add it to the Tracked Missions list. Now you can more easily track important mission cooldowns in one place.
New official developer site: http://games.jupath.me/tsw/available-missions
Source code is available via git from curseforge.
If possible, please try to use the official forum for discussion in order to consolidate potentially useful information in one place.
