We want to make it easy for you to switch between Placker and Trello, this is what we created for you to make it easier:
The google chrome extension will add a button to Chrome that will take you from Trello to Placker in one click.
Get it on http://ganttfortrello.com
The Trello power-up will add two buttons to your Trello board, one will take you directly to the Gantt chart, the other will take you to your Trackers.
We are currently testing the power-up, read more on how to start using it here.
