Sure. It’s quite simple…the tag would enable me to find all tagged milestones in an Advanced Search…assuming I am diligent in maintaining those tags. (Right now, there is no other way to find Milestones.) It’s helpful to use such a search, as then I can:
- Look at all my milestones in one place…do they make sense? Are they complete and consistent?
- Bulk edit them (such as to “multi-home” them in other or additional projects - as that is the only way to see such milestones in other projects)
- Export them
Please note that I don’t think tagging “Milestone” type tasks with a tag that says “milestone” is a great thing to do. It isn’t. I would much rather run my searches off of inherent properties of entities, not off of logically superfluous tags that I have had to create, manage and maintain. It’s just not possible right now. Asana’s data model treats every instance of filtering or sorting of any field or property (such as the unique Task type of “Milestone”) as a special case, requiring a special new feature to be developed for it.
