FAQ
Q: How do i access the Configuration?
A: You can open the configuration with the Slash Commands (/bt or /bartender) or through the Bartender4 LDB plugin.

Q: Where are my keybindings? And how do i bind new keys?
A: Bartender4 buttons do not automatically inherit keybindings from the Blizzard bars (except for Bar 1), you have to use the new KeyBound to re-bind your keys. You can access KeyBound by its slash command (/kb) or through the button in the BT4 config. Hover a button, press key → voila!

Q: Can I skin the buttons beyond the built-in options?
A: Bartender4 allows skinning through Masque! After installing both Bartender4 and Masque, you can customize the BT4 appearance in the Masque options.

Q: How do i disable the snapping of the bars?
A: Currently, you can temporarily override the snapping by holding down the Shift Key while moving your bars, or uncheck the option in the popup when your bars are unlocked.
