Gantt Chart/Kalender view. It would be extremely helpful to see tasks as bar with begin and end-date within a calendar. This would make your sub-tasks extremely valuable, because you could visualize dependencies. In fact, this would bring Toodledoo to a completly new level. Look for the implemented Gantt Chart tool of Mindmanager. This with toodledoo would be nearly perfect
The task square checkbox is solid gray when printed. It used to be just the outline of a square and it was easy to use it as a checkbox. Please bring back the transparent checkbox.
Define monthly repeats on a particular day of the month
e.g Repeat on 15th of every month regardless of when completed
Dividers by day
Currently Toodledo displays tasks by today, tomorrow and then one divider for the next seven days. Please provide daily dividers for seven days (i.e., one divider for each day).
Link phone photo to a task
I often take a photo of something to buy or fix or of a business card or a screenshot of someone else's phone then create a task referencing that photo. Currently I either enter "See Photo on 20180101" or the photo name. It would be nice to quickly link a photo to a task.
Integration of Scheduler with Outlook Calendar
I love Toodle-Do and make heavy use of the ability to sort tasks by Importance, and also of the Scheduler function. It would be fantastic if Toodle-Do Scheduler could cooperate with Outlook Calendar in such a way that it could block out time for each task (around existing Outlook Calendar commitments, and scheduled for each users' working hours - which they'd have to provide in advance obviously) and possibly flag up if there "aren't enough hours in the day" - ie there's not time to fit all tasks in ahead of their deadlines... I know - a massive ask in terms of development, but it would be a massive leap forward in terms of productivity.
Repeating tasks: Weekday or Working Day before/after a given date
Add the ability to make a task due on the last/first weekday before/after a given date. For example, paychecks are usually due on the 15th of the month. However, if the 15th is a Saturday or Sunday, we need to do them on the 14th or 13th. This could be generalized where user sets his or her "Working Days" and then we check Last Working Day on or before a specific date. The paycheck task, therefore, would be set to "Repeat Monthly on the last working day on or before the 15th". Conversely, government payments due on a weekend are usually remitted on the Monday (or Tuesday if Monday is a holiday) after the weekend. So in this case, we'd want to set First Working Day On or After a specific date (e.g., repeat monthly on the first working day on or after the 15th of the month).
Enable option to configure colors on the rows, in order to easily detect which tasks are nearing expiration or are already expired.
A calendar view gantt chart hybrid. This way I could have a daily view of tasks currently in process, not just tasks due (currently in calendar) or duration of tasks.
