nah I couldn't update it as I didn't knew the necessary tags at the time - it's just the stock button what you see in the LM DF Revisited.
Speaking of tags.. these might help you out hehe:
Code:
<PanelFile ID="ID_UISkin_GamePlay_MountDisplayBox">
...
<Element ID="MountDisplayField_DismountButton" X="58" Y="51" Width="115" Height="29">
<Element ID="Button_MountTheme_left" X="0" Y="0" Width="24" Height="29"> </Element>
<Element ID="Button_MountTheme_middle" X="24" Y="0" Width="67" Height="29"> </Element>
<Element ID="Button_MountTheme_right" X="91" Y="0" Width="24" Height="29"> </Element>
<Element ID="MountDisplayField_Button_Label" X="18" Y="3" Width="79" Height="20"> </Element>
</Element>
<Element ID="MountPipDisplayField" X="0" Y="0" Width="90" Height="42"> </Element>
