Just curious to know when this feature will be added ?

@Moxville We did not start implementing this since we were unsure if it would be better to separate anything time related (reminders / deadlines) into a new calendar component, since many people like the simplicity of the current Todo UI. However since a good calendar will probably take a long time to implement, it might be worth to improve the Todo List first, and then potentially merge it into the calendar component at some later point in time. If you have any concrete ideas on the functionalities of the improved tasks, let us know! Even sketches on how the UI should look like are very welcome and will surely be considered during development.
