Trello and Google Calendar – Update Frequency of Trello Webcal Page

Google says every few hours, which in my experience means 6-24.

Currently, calendar feeds are automatically updated by Google Calendar every few hours. We understand that some users want to have the ability to refresh the calendars they added manually and we are exploring various ways to enable this.

If the calendar you're subscribing to using Google Calendar isn't refreshed after 24 hours, please send us the calendar address and the detail of the problem so that we can investigate.

There are only up to 5 or 6 lists that can be viewable at the same time.

So the two options would be to use:

• A Card as the feature and the description for user stories
• A List as the feature and Card for user stories

In the first option I would imagine it would have to be something like

Here you would need to add up the points manually (Or create a userscript/extenstion see next option).

In the second option you can use this Chrome Extension to take care of your user points and let cards handle user stories. As you said this can be come unmanageable with next up/in progress/review/ so then you would have to keep the tracking cards to the left and the feature to the right on your board. When a new activity appears on a board ensure it is "bubbled" to the left as the most recent feature update. Assigning members can also ensure nothing is forgotten.
