When you change the defaults from Heartbeat you can not export Overriden values with Features, only new content. I realize this must be because of the conflict between the modules providing the defaults.

What would be the best way to change the defaults for the templates in the "Heartbeat activity defaults" module for a custom install profile? Should I export the changes one by one and then try to import the changes in the install profile or module? That is the only way I can see.

Cheers heartbeat is working great btw, love the views support.
