Free task manager app Trello has got better with power-ups. Trello has introduced few additional features (called Powerups) which are optional and can be enabled as per your need.
Check the Trello Introduction here
These new power-ups include – Voting, Card Aging, Calender
These Power-ups can be accessed from Sidebar > Menu –
Voting is an existing functionality which has now become optional, apart from it remaining two Card Aging and Calender are new on Trello.
Card Aging allows you two settings – Regular Mode (Older Cards will appear more transparent) and Pirate Mode ( Older task will have more cracks and tears).
Trello always needed functionality to add tasks to Calender and get reminders for Due Dates. For addressing these requirements Trello Power-ups have finally got Calender, which will show all tasks with due dates on it.
However you will still miss a reminder service from Trello.
