Very Nice!! 
Personal Changes:
1.
<include>eq2ui_mainhud_performancepanel.xml</include>
moved from "eq2ui_mainhud_startbutton.xml" to "eq2ui_mainhud.xml". The startbutton window is an inappropriate place for include statements.
2.
eq2ui_mainhud_startbutton.xml was deleted, not being used.
3. Moved the following files to the subdirectory "performance/":
eq2ui_custompreset1.xml
eq2ui_custompreset2.xml
eq2ui_custompreset3.xml
eq2ui_muteall.xml
eq2ui_mutemusic.xml
eq2_recent.ini
presets.exe
preset_parser.exe
4. Edited lines 3-12 in "eq2ui_mainhud_performancepanel.xml"
Code:
<include>performance/eq2ui_custompreset1.xml</include>
<include>performance/eq2ui_custompreset1.xml</include>
<include>performance/eq2ui_custompreset2.xml</include>
<include>performance/eq2ui_custompreset2.xml</include>
<include>performance/eq2ui_custompreset3.xml</include>
<include>performance/eq2ui_custompreset3.xml</include>
<include>performance/eq2ui_mutemusic.xml</include>
<include>performance/eq2ui_mutemusic.xml</include>
<include>performance/eq2ui_muteall.xml</include>
<include>performance/eq2ui_muteall.xml</include>
