Filter todos by manual add
Today on https://gitlab.com/dashboard/todos, I can filter my todos by `Any action`, `Assigned`, or `Mentioned`. I currently can't filter to issues I've manually added a todo to.
For some workflows, it is very helpful to quickly view the todos that I've manually added, as those are ones I intended to return to.

Actions:
- Any action
- Assigned
- Mentioned
- Added
- Pipelines
(This idea came from a brainstorm between @dzaporozhets @cperessini @tauriedavis @pedroms @sarahod @dimitrieh @awhildy at the 2017 GitLab summit)
