Hi.
For start you need to change the width and height,look for the 2 line code in the begining:
example:
<PanelFile ID="toolbar">
<Element ID="ToolbarField" X="0" Y="0" Width="1440" Height="900" Detach="1">
Change the width="1440" to 1920 and the height="900" to 1080.
Before you start modifying the code,use my 1680x1050 code for fresh start then modify it to your resolution.
Don't modify anything else yet,this will make all the menu button's to top left.
Log in to the game to see if the basic layout is ok,the main bar should be
very bottom of the screen now and menu buttons far top left.
After that you just need to modify the location of the attack button,fervor in which you will have to figure it out how far you want it to be on the screen which you might already have the basic idea how to move things based what you said.
For the main bar(toolbar) level meter to be moved you need to modify first the X= or the Y= code, a X="0" will make things go far left side:
<Element ID="Toolbar_Quickslot" X="628" Y="1000" Width="420" Height="37"></Element>
and
<Element ID="LevelMeter" X="629" Y="1039" Width="420" Height="10">
Hope this will help you set on the right track.
Thanks for using my UI.
