Improve Milestones application
a 'backlog' view where you can see all To-Do's that have not been linked to a milestone
Kanban view per milestone, if I create a milestone and got 30 to-do's linked to them, I want to be able to click on my milestone which will open a Kanban view, that contains only the linked to-do's
Milestones need to look like To-Dos, where To-Do groups are Milestones with progress bar (https://freedcamp.uservoice.com/forums/126945-suggestions-for-features/suggestions/6700230-milestone-progress-bar), priority etc, with options to drag and drop tasks between milestones and ability to slide unassigned task on bottom or right side to be able to drop these tasks to Milestones.
Should also allow to add new tasks directly from Milestones tab. Users also asked us to add options:
- to add a full To-Do group to a Milestone with one click
- have cross-project milestones - probably Project Group Milestones containing inside Project Milestones - https://freedcamp.uservoice.com/forums/126945-suggestions-for-features/suggestions/6523807-milestones-for-groups
