I know this is supposed to be a temporary topic, but since you suggest the changes shown in your screenshots, I thought I'd go ahead and submit a couple of line addition suggestions for both Innkeeper.lua and Mailbox.lua.
I just got my mage to Uldum and noticed that no icons for the inn or the mailbox were added in Ramkahen. Also, Uldum isn't in either file with any locations, so I added the following coordinate additions for these places in their respective files.
Mailbox.lua: added at line 74,
Lua Code:
[720] = "0,55,33.8|0,26.7,7.9",
Innkeeper.lua: added at line 75,
Lua Code:
[720] = "0,54.6,32.8|0,26.6,7.2|0,22,64.5",
I will add more coordinates as I come across them.
I hope this helps. If there is a place where suggestions like these should be posted rather than creating new threads or picking what looks like the best place to post, please let me know.
