Before you can write any sort of code, you'll want to have a tool that lets you edit your AddOn files. However do not get overly distracted with the tools themselves while trying to get your first AddOn created. Any text editor, like Windows Notepad can edit the files. All AddOn files are plain text files. The editors can make the coding and many repetitive tasks easier for day to day editing, but it's often very difficult to learn the tools and try to learn the AddOn at the same time.

I like doing achievements – and some achievements are not covered by the guide. Obviously there are lots of them. Often when you think of doing something special, it includes coordinates and places. Would it be possible to have a feature in the guide where you can plot in one or preferably a list of coordinates where you want to go, call it something, and then be allowed to run it through the awsome guide system? – the Taxi feature that directs me the fastest way to a location is fantastic. For the list of coordinates I would want two options. a) any order and b) need to be in this order.
The World of Warcraft API has a list of functions that you can interact with and to talk with WoW using Lua. These are your building blocks for manipulating WoW windows and chat boxes and so forth. Looking at these for the first time can be very daunting. But don't be discouraged. After getting more familiar with Lua the WoW API gets much easier, and the documentation gets much easier to read. Keep in mind there are many different ways to accomplish your goals, so when going though the API keep looking until you find a way that best suits what you need.
Bartender permet de personnaliser directement vos barres d'actions ainsi que les éléments de l'interface de WoW.
