Supersized - full screen background slideshow

we have 21 TYPO3 languages in our installation. Adding the plugin to a page will show the Plugin Options for ALL Languages.

Editing this plugin in Backend is loading extremly slow and, depending on System sesttings, the big number of InputFields reaches max. allowed field length, so the plugin cannot be stored.

This Problem can easily be solved:
change in :
\typo3conf\ext\frsupersized\Configuration\FlexForms\flexform_supersized.xml

<T3DataStructure>
<meta>
</meta>
<sheets>

to

<T3DataStructure>
<meta>
<langDisable>1</langDisable>
<langChildren>1</langChildren>
</meta>
<sheets>
