Have you tried iMindMap (www.thinkbuzan.com)? Pretty sure it does that.

Thanks for your comments - much appreciated!

> Will there ever be time tracking? That's one feature I really wish Trello had by default.

We are currently considering all feature requests and this is one I've heard a few times. As such, it is definitely something we will consider!

> Does it have dependencies?

Not as yet, but this is an early release of the product and we are aggressively adding new features and improvements. This is definitely something we are considering.

Thanks for your comments. Some kind of 'quick-add' for tasks and groups is definitely something we are considering.

> What's the stack behind this? Very nice by the way!

The entire app is written in CoffeScript - we're using Node.js on the backend and the front is mainly SVG/D3.js/Backbone.js.

Thanks!

> This might be a bug, or not. If I have 2 groups with different colors and put one inside the other, the inner group changes color. Did not expect this behavior.

This is by design - we simply could not get the visuals to look at all decent with mixed colours for nested groups. The idea is that the one colour applies for the entire category.

Ok, that's fine!

Thanks for the clearification.

Thanks for this. I personally like just clicking off to dismiss the modal, but admittedly if we keep this we need to be a bit cleverer in terms of not just losing the changes.

> I played with it a bit and unless I missed something, the size of the circle is only related to how many other circles are inside it.

This is true - the group (used to categorize task circles) grows to fit the content. We did play with allowing task circles to be resized to show priority/effort, etc, but couldn't get it to work well. We may revisit it, though.

Founder at DropTask here. Thanks for your comments, we'll give them some thought.

In terms of how we will survive, as Ygg2 has posted from our FAQ, we plan on charging for premium features and business accounts which will offer team administration/reporting, etc. In the meantime, we are well funded :-)
