I know that add-on's for this have come and gone, but there is either not enough information on them, or the addon simply doesn't work (because it is old). What I did is combine some features I like in Legion Honor and the Titan bar to give a bigger picture of what's happening with honor. 

Currently this add-on tracks total honorable kills, honor / honor needed to level, honor per hour, honor this session, time to next level, and a customization goal.

To use the custom goal, type /titanhonor goal ####

Obviously replace the #### with your goal for the day. For example, I usually set a goal of 1000 honor every day when I log in, that way I know if I at least hit that much.

Please let me know if you have any ideas of what to add, if there would be anything useful to see, I'll consider adding it. My next addition will probably be a toggle for Honor Level on the bar.
