In a large and/or long-lasting project, and depending on how milestones are used, there may be a good number of milestones within a project. Currently, the Milestones page only supports a quick filter by open, closed or all, but none of those options will help you find a milestone quickly if there are many of them. It'd be nice if there was a "quick search" textbox that allowed you to type some keyword text to search milestones and quickly display the results.
Create a quick search textbox on the Milestones page (under Issues) so the user can find milestones by text match.

Use the quick search textbox to quickly find milestones with the matching text in the title or description. If you have many milestones, this will allow you a fast method to locate the milestone of concern.
