@LORBY_SI
Thanks for the quick answer.
Will there be a short instruction for AAO 2024 Which xml-files have to copied and renamed? (I think ConfigDatabase_MSFS.xml and UserScripts_MSFS.xml are the most important ones, but there are some more in the folder ... )
If, as you wrote, sim events and variables like LVars, and HVars still work as like in MSFS 2020 that would be great. As IEs can be used for most BVars the latter would not be so important for me.
