It would be very powerful if we could input multiple numbers for parameters at least for Generator`s Limits.
This was implemented in RC5:- Generator->"Limit by Material ID" now is a text input, accepting single values, ranges and multiple entries separated by commas. For example: "1,3,5-8".
In fact, it will be good if we can have a roadmap for RC6 so we don`t double enhancement requests each time.
All your suggestions and considered and added to our wishlist, but for several reasons this list is not public.
Anyway, don't worry to request some feature multiple times. If other users see the post and need it, we may change the priority.
