The ability to use formula (particularly date formula) in email snapshot variables.
Consider a dashboard that displays data from a rolling 30 day window, requiring a 'startDate' variable of format 'yyyy-MM-dd'. Right now this variable has to be updated manually everyday, causing extra work. This is multiplied when there are more variables on the dashboard, as is usually the case.
Ideal: Full use of formula within email snapsnot variables
Halfway option: A special set of reserved strings which can be used, and are interpreted and replaced by Klipfolio when the email is generated. Such as LAST_N_DAYS:30, LAST_N_YEARS:2 (much like SOQL).
Calculation of all dashboard variables before email snapshot is sent.
My dashboards have a control klip which set the values of around 6 variables as soon as the dashboard loads. These variables are used by all other klips in the dashboard. This works perfectly within the app, but breaks in an email snapshot. For some reason, the variables are calculated within the klip but NOT sent to the other klips.
Because of this I have to create email versions (where the variables are hardcoded) of all my dashboards. This requires extra time, and might push me over the dashboard limit for my pricing plan.
Calculate all the variable values, and acknowledge the 'dashboard level' scope, before generating the email snapshot.
