From email: suggestion to add milestones

this came by email

I use your program at work and it is a really great application for managing certain projects.

What I miss is adding / displaying milestones (with some small description) for a certain date.

Please consider adding this feature in future updates.

Is anything wrong with our existing milestone tasks?

Thanks for teaching me how to add milestone. I tried, but…
Well It would be great to have milestones displayed as line (not point) across all task. Something similar like “today” red line. And it would be great that once you hoover mouse over it it displays name + notes. But this is only my humble opinion.
