It would be nice if the "From" date is not required. Milestones often don't have a start date, but only a completion/target date.

I think it would also be better if you combine the "Reschedule" and "Edit" option, and display an "Edit" link behind the Milestone name, immediately on the first page after you click one the Milestone tab, otherwise, if I want to just edit (reschedule) a milestone date, I have to first click on the Milestone tab, then on the Milestone name, then on the "Reschedule" option.

Also, when I finally click on the "Reschedule" option for a specific Milestone, and land on the "Reschedule milestone" page, it is not exactly clear on which Milestone I am, unless I check the breadcrumbs. It would be better to add the Milestone name as a header above the date options on the "Reschedule milestone" page.

I need the start date for the Milestones to remain, projects do not always start immediately and it does matter to us when the start date is. Resources need to be available from a certain date.

What would be nice is if you could choose a start time and end time. Not just the day, this could then link into time tracking.

We have a requirement to record the exact time something was finished. For example, if a project manager had a deadline of 4pm and we wanted to check whether it was completed on time..

Great, thanks for the tip.
