i've been a 10 more year user of redmine and recently switching to OneDev, great project !!

one last lacking feature is the time tracking :

• ability to add hours each time an issue is modified.
• total hours spent on an issue are sum to be part of total hours spent on a milestone.
• total hours spent on a milestone are sum to be total hours spent on a project
• when an issue is removed, ask what to do : report the total hours spent to the milestone or not
• when an milestone is removed : ask what to do : report the total jours spent to the project or not
