Are you tired of the default themes and just going to Standard Dark? Well, this might be of interest to you! I've made many custom themes (13 currently!) that you can use to customize your quest book.
How to install: Put the resources folder from the zip into the resources folder in the betterquesting config folder. Make sure to reload your textures (or put it in before you load the game) for them to load properly. After that, you can select any of the themes from the menu.
How to change colors (if you want to change it from the color themes from my pack): Find the image files through the subfolders (you can't miss them) and open using any image editing software. If you do make changes, please do not redistribute them. Match them to the way you want for your client. F3+T can reload textures ingame.
More themes coming soon!
