Addon Ideas
Every so often I have a brain storm and start playing with possible addons that don't seem to be out there. Primarily because I was looking for said addons functionality. As I recall the ones I have been playing with I will add them here.

It basically will allow the inscriber to see exactly which of the known glyphs are missing from their repertoire so that they will know whether or not they need to learn more.

It is currently in the early stages with it correctly recognising an inscriber and generating a list of known glyphs and whether the inscriber can make it or not.

Legion Update: As you can see this idea never got off the ground. So dependant on usefulness of the profession I may not go forward with this idea.

Separate Quest Trackers
I noticed that they now have a Super Tracker for the current active quest, World Quests, Zone Quests, Profession Quests etc that I am considering updating my objective tracker addon so that it separates the objective tracker into multiple individual frames / collapsible sections so that you always have access to the quests you are interested in, whether a scenario, dungeon, raid, zone etc. Hopefully their API changes will make this easier to do now than it was before I left when I was looking into updating my objective tracker addon. It will most likely involve a re-write and if necessary a separate addon so as not to affect the nUI compatible one currently available.
