2006 Interface

Setup:

1. Go to the "Interface Styles" plugin on Runelite and select the 2005/2006 Gameframe.

5. Select "First" here:

6. Disable then enable the resource packs plugin

Done!

If any of my changes are not to your liking, simply go into the 2005/2006 folder and delete whichever files you didn't like and it'll revert back to Runelite's version. Then just turn Resource packs plugin off and on again.
