Connection with Trello
A connection with the task manager Trello would be great. It could show all dates within trello or at least the tasks from Trello.

I would love to see sync between tasks in the BC2 app all Trello cards that are assigned to me with a due date attached to it.
The comment from Jim Below is very helpful and it works fine
If the official Trello app is not sufficient, an connector providing CalDav access to the Trello API might be more universal, since multiple devices / calendar apps could be connected with it.

For a read-only view of your cards in any calendar app, yyou can use the Trello Calendar power-up (though you need to be using the browser version of the site, not the Android app to enable it). It exports an iCalenda URL you can easily add to Google Calendar (from the Google calendar site, not from within Business Calendar. From that point on, it just looks like any other read-only calendar in your Google account, visible in Business Calendar.
Deeper integration is a very good idea, but maybe this gets you part way there?
