Notes associated with time tracking of tasks

In addition to adding tasks, I'd love to add time to some note. It is optional. For tasks, in which timer is added, Notejoy can also be used as project management tool. I vision to see Notejoy as a product that supports (Task Management, Time Tracking, Notes). I wouldn't want to use 3 apps like Trello/Slack/other Task/Time management/Project Management tools & integrate.

By timeline, I mean to add duration to a task (like a timer). It could be hours/days/weeks/months depending on project.
