Hey all-
Sunthas and I exchanged some private messages and I gained blessing to post this here.
I made a windows script that automates the process of copying over the mainhud to your custome ui folder and then it addes the needed <include> line to the end.
Now it's not currently hosted on EQ2 Interface; but
here is a link to it.
Contains 3 sample images of the script in action, readme file, and the script itself.
You may [will] need to edit the .vbs file to chagne some variables about your setup (EQ2 install path, name of custom ui folder, etc).
Have fun!
