I upgraded and yes I did own most of the extensions as I am a super suite owneer.
Got to say that a few issues I had unresolved with Menu writer as a seperate extension are no longer an issue. The single install is a breeze just like MXKollection used to be :)
I just hope that more will be added and that dixes and upgrades will be faster in appearing. The length of time for fixes to be made available is essential.
