How do I hide the description area in property window
By tweaking the preferences of the "showDescriptionArea". In any layer.xml file (for example the one of branding) add
<folder name="Preferences">
<folder name="org">
<folder name="openide">
<file name="explorer.properties" url="explorer.properties"/>
</folder>
</folder>
</folder>
and then next to your layer.xml file create the explorer.properties that contains:
showDescriptionArea=false
sortOrder=0
I found this by looking at the PropUtils class in the NBP sources.
