It would be great to have the ability to configure the date time picker' and 'date picker fields' field behaviour to set filters or limits depending on business requirements:
1) For some project request, we regularly have a freeze time. We would like to have a function to set limited available date/date time could be selected from the calendar in the Date / Date Time Picker custom field while submit the request.
2) Fix version release date (similar case https://jira.atlassian.com/browse/JRASERVER-22640:
"Our developers work on multiple projects that each have their own version release dates. I would like to create a filter for my developers where it shows all issues that have a Fix Version release date between now and 1 month in the future."
