Nothing really! The fact they provide great documentation for their products helps me understand them better so I'm able to implement what's required without any issues at all (actually none).
So far it seems like no project management features are needed as long there isn't much automation involved - which we're not doing right now but will be soon enough once our needs grow :) Haven’t encountered anything bad about conden yet though ;) Would definitely recommend considering using this product if your team has people who would prefer something simple than coding themselves or just those used-to having everything automated already :D.
