Hello Etienne
The work on the new Template installer has been completed for testing in SVN 544.
Be aware that the templateDetail.xml file has to be modified to be working with the new installer. This has been done to avoid problems with Joomla template files.
change the following in your templateDetail.xml.
<mosinstall type="rsgTemplate">
various fixes have been done about voting and commenting in SVN556.
The permissions for voting per gallery have changed as well.
Please note that some changes to the database have to be applied to use that feature. see (sql/upgrade_1.14.0_to_1.14.1.sql)
