I quite often build a template that includes events / descriptions / headlines based on the location or other fields. This is easy to do but can be a bit messy if one of the fields is empty as it will leave a spare comma or other punctuation.
This could be addressed by, eg, allowing the inclusion of punctuation at the end of the variable name ( eg, {event,} ) and if the field is empty, the {event,} macro is also empty.
There may be more general ways of approaching this issue, but I would find the facility useful.
