Here is a simple custom window to get you started. There is no automation at all -- you can edit widths, colors, text etc. in the UIBuilder very easily.
1. Drop the unzipped file into your DarqUI_v3 folder
2. Use Notepad to add this line to eq2ui_custom.xml
3. Log in and type
To create a second window, copy it and call it Categories2 for example.
