See attached. If you use ProfitUI, just extract into your ProfitUI folder. If you use another UI comprising an eq2ui_custom.xml file, you need to merge them (you only need the _Styles and _AutoAttackCalc lines from mine). You can resize it to show only the numbers. Background and frame can be controlled via the sliders in the windowsettings. You need to keep the mouse over the variable you want to edit.
Let me know if this works how you expected. If it does, I'll make a separate release with it an add it to ProfitUI.
EDIT: Doh, forgot to mention, you can show the window via:
/show_window Custom.ProfitUI_AutoAttackCalc
