if this is the ui you mean
http://www.lotrointerface.com/downlo...53-DarkUI.html
Then try this. Im a relative xml noob myself but i did add the 2 new buttons. had to adjust the height of the toolbar field to make room. The default was for resolution 1680 x 1050 so you may have to readjust if you use another resolution.
Just drop the new Skindefinition.xml in you Ui folder and replace the old one.
Please let me know if it works alright
