We should have an update to the V2 Templates solution available early in the new year that will allow you to disable the Options menu by editing the value of a constant. I’ll let you know when this is available (I’m suspecting within the first few weeks of next year).
We don’t have any plans to remove compatability with any existing applets in new versions of Formativ. All existing 1.5/1.6 version applets are compatible with version 2.0.
I hope this helps.
