DISCORD
I have created a Discord server which people can use to report issues they find with this addon: https://discord.gg/BGKnpza
ABOUT
This is a very simple addon which shows your current XP and XP to next level on your experience bar, as well as whether or not you are rested; if you are, it will display how much rested XP you have left.
If you're a Hunter, it will also display your pet's current XP and XP to next level.
You can choose whether or not to always show the information, or only show it when you hover over the experience bar; you can also choose how much information is shown, and whether or not to separate numbers using commas for easier reading.
You can access the configuration menu by using the /xpt command.
