I think a really cool feature, and potential a way to start competing with some other apps beyond “to-do” list apps, would be to add a notes section / feature into Asana. I know there already exists the Comments feature on specific tasks and Conversations feature under projects, but I am thinking of a fully blown out Note-taking capability (akin to Evernote) that can be captured and saved in Asana.
Example use case: I sit in a lot of meetings, and I capture notes often in another program (Google Doc, Evernote, etc.). Later, I have to come through these notes, and manually add these into Asana. However, if Asana had a module that allowed for long-form note taking, these notes could exist under the appropriate projects / teams without having to go to another program.
Having Notes in the same program by itself would be convenient, but not altogether life-changing. However, once that base is built, you can really gain productivity efficiencies if this Notes section also had functionality, such as the ability to highlight a line or sentence in the notes and quick add a task under that same project the notes were about. The task could also have a link tying it back to the notes for others on the team to reference, if they are assigned the task coming out of the notes from a given meeting.
There are probably dozens of other unique functionalities that you could add into a more robust Notes tool / section, if it existed.
To reiterate, I know Comments on tasks exist, and I know Conversations within projects are possible, but I imagine a Notes section (that might sit next to the features like Timeline, Conversations, etc.) with more robust capabilities unique to capturing long-form notes from meetings or brainstorms.
