Almost there!

When you select more than two projects in Gantt Chart display and then select for Week display, the second project dates get massed up.
There are a few more things I wish they work on it. But I like this app because you can start making your Gantt charts using this app. That is what need. I dont want to use another software in my computer to make a Gantt chart, then upload the file to my phone. That is nonsense to me.
