due to many requests and questions about the workings of ORBXs FTX Central combined with add-on.xml files, a new feature has been added to the P4AO.
You can now move multiple scenery entries to an add-on.xml file or back by using the "Multi-Select" option and the right-click context menu.
Additionally a new button has been implemented that will "Remove duplicates", meaning that it will remove all entries from the scenery.cfg that are also present as an add-on.xml definition.
With these two features combined you can move all ORBX scenery.cfg entries to an add-on.xml file in one go. When you use FTX Central the next time, it will reinstate the entries in the scenery.cfg - now all you have to do is to start the P4AO again and press "Remove duplicates" - this will reduce the scenery.cfg once again to only contain those ORBX entries that are not already present in the add-on.xml.
