Hi, 
should I add a blueprint for the first one (indicators in custom forms)?

The indicator functions for 2.21 looks great. I’d like to suggest as well "floor" (similar to Math.floor()) - combined with daysBetween, you can then also calculate other period types as in age in years = d2.floor(d2.daysBetween(birth, death)/365), duration of pregnancy in weeks etc etc.

Similarly, I imagine "ceil" and "round" (or some function where you specify number of decimal digits) could we very useful.

Thanks
Olav

As far as I can see this is not possible currently with program indicators.  I think this would also be very useful for the program rules, e.g. you have two dates and would like to enable/disabled fields or sections based on the different between them. In my particular case, I'm looking at cause of death registration and would like certain fields to be active only if the age is < 1 year based on date of birth and death.
