Looks like a good project. Congrats.
I know this is a gantt chart, but one thing I find
lacking in nearly all implementations is the ability to
assign a "cost" to a task and a "budget" to a project.
This would allow people to "manage" their cashflow as
well as their time, which for me is MORE important.
(You can have all the time you want, but if you don't
have the money to complete a project ... you are stuck!!!)
This is very important for small businesses that
actually have a budget to work from!
