I expected the integration links to tell me what each integration can do rather than take me to a login form. The ideal project management tool for me would integrate with the tools I use to do the work being tracked, and ML to automatically log everything in the project management tool. Kata lets you send updates from your other application using special comments, but I would prefer not to even have to do that.
We're also planning to continue adding more integrations over time so more of your work can be logged automatically- we talk about this a bit more in some other comments here. It does take time and effort to get (and keep) those functioning though and half the time we make an integration it gets less usage than you might expect. Still, we're always interested in learning about more tools that our users would find value in integrating.
