If you are looking for a minimalistic UI you should check my
Yessh UI
If you want you can have
skinless vitals and smaller strait
focus/fervor bars There are others mods with smaller fervor/focus bars, don't remember the names.
You can hide the auto attack indicator
<Element ID="AutoAttackIndicatorButton" X="0" Y="0" Width="1" Height="1"></Element>
<Element ID="ViolentModeIndicator" X="0" Y="0" Width="1" Height="1"></Element>
<Element ID="ToolbarButton_AutoAttack_TutorialHighlight" X="0" Y="0" Width="1" Height="1" />
And also hide the XP bar:
<Mapping ArtAssetID="LetterBoxBottom" FileName="invisible.tga"></Mapping>
or better:
<Element ID=""LevelMeter"" X="0" Y="0" Width="1" Height="1">
<Element ID="LevelMeterFill" X="0" Y="0" Width="1" Height="1">
<Element ID="LevelMeter_BonusMeter" X="0" Y="0" Width="1" Height="1" />
</Element>
<Element ID="ToolbarButton_LevelUpXP_TutorialHighlight" X="0" Y="0" Width="1" Height="1" />
<Element ID="ToolbarButton_Experience_TutorialHighlight" X="0" Y="0" Width="1" Height="1" />
<Element ID="LevelMeterText" X="0" Y="0" Width="1" Height="1" />
</Element>
Finally not to bother with the default unmovable quick slot bar, I would hide it completely
<Element ID="Toolbar_Quickslot" X="0" Y="0" Width="1" Height="1" />
In your UI I would hide everything on the left of the quick slot bars as you can have access to all this with hot keys.
