It would be nice if we could share a project with specific rights.
For example, grant somebody just read only rights.
Or allow people to only resolve tasks and not create tasks.
Thank you for your feedback. The best place for suggestions would be the vote box https://todoist.com/Vote/ as it allows you to submit a feature request and have other Todoist users vote for your suggestion. Please feel free to submit one in there.
Thank you for the fast response.
I see there is already a vote (http://todoist.com/Vote/show/6939/)
Is there a place where we can see what is already implemented from the votes?
Not directly. When we implement a feature from the Votebox, we reply in the Votebox thread and everyone who participated in it will be notified via email.
Also, every big update (that introduces a feature and doesn't just fix a glitch or a bug) is announced on our social media channels (Facebook, Google+, Twitter).
+1 Yes, this would really be helpful.
