The mobile version of todoist is a pain to use on the iphone because the text is so small. I'd love to see an iphone version that takes advantage of the features available on everyone's favorite phone. :)

Plugin like RTM to see tasks in Google Calendar

Move Todoist into a team based task manager

Not sure how many other list makers do this, but I typically use 3 status markers:
1. "to do" = not started
2. "in progress"
3. "complete"
The tick box in ToDoIst only allows states 1 and 3. Could we have an option to enable a middle state. i.e. toggle 1. -> 2. -> 3. -> 1.

Todoist needs RSS feeds.
For example a feed for items due tomorrow, in the next three days, overdue, etc etc.
This shouldn't be too hard to implement at all, as far as I can imagine.

I think that this will distort the discussion of new features here. If people dont joint the discussion in a positive way and even vote anonymously I cant see how to take their voices serious. If 95% of the votes for a feature are anonymous it would be very hard for me as a developer to count this votes in. We are not running political elections here where anonimity is a "must-have"-feature.

The mobile web interface is too slow. A Todoist Blackberry Application where the interface to find/sort tasks will be similar to the web application, this would imply a Todoist/Blackberry sync as well.

Send items to Todoist via email or text message.

See all tasks in a timeline

I have default page set to 'od,tod,tom'. And thus to create a new task I need first to switch to some project's page.
It would be much more smooth if it were possible to create a new task on whatever page you are at (specifying target project in a drop-down, for example)

Create a mini calendar that makes it possible to insert date and times graphically

Let's not overcomplicate things as Todoist is pretty great as it is! Thanks!

i use the order of items to show chronology of what I'll do when. I'd like to be able to order my list even if its a "today" list or a list created based on priority.

Allow users of both services to enter Todoist items through Jott, and possibly to send reminders from Todoist to Jott.
