I love Github, but they need to build out more serious features into their issue tracker for it to be useful as a software estimation tool. Specifically I need:
* Time estimation.
* GRANTT charts.
* Time estimation.
* GRANTT charts.
Serious answer: Issues are not--to my knowledge--a software estimation tool. I have worked for decades in estimation-oriented development environments, and in my (anecdotal) experience, it is a mistake to use the same tool for both estimation and delivery.
It is seductive for them to be the same thing, as you can feed actual times back into your project, but the conclusion I've drawn is that the estimate reflects a kind of "interface" visible to the outside world, while the issues reflect an "implementation" visible to the team.
When they are the same thing, you end up doing a lot of work fiddling with the estimate to keep it congruent with the internal tasks, even when that congruence is not relevant to the delivery date(s).
I realize that this is heterodoxy.

I hope they are very careful about adding features and would rather see them focus on trimming less useful features.
