I need to know task a is blocking task b. But they are separate tasks not sub tasks.
Then if I schedule task b for example it can highlight task a hasn't been scheduled yet. Or shows me if a is scheduled after b etc

Some tasks are related together and have some dependencies, for example if you want to install software in Linux in pc that it doesn't have OS you should install linux first then installation of software depends on previous task it's crusial to in sequence. It's not subtask it can be a big task to do , it was just example.

Thanks for sharing this idea. I extended further on this idea & suggested this feature - https://anydo.uservoice.com/forums/143587-general/suggestions/44946961-product-task-dependencies-with-duration-gantt-d

There are always tasks that are grouped together for example a list of tasks I got to do at a particular time or a particular place or one tasks depends on the outcome of another. These tasks occur everyday and if we link or group them, we should be able to move them together. Kinda what happens in Google keep. They are not really sub tasks and we'd like to see them individually on the list but we should be able to move them together.

This is essentially what I need. The dependent task could have relative time specified (eg the Nth 7am after completion of the prerequisite task; or the Nth Wednesday or the Nth occurrence of the Xth day of a month; etc). With relative date/time specified, it wouldn't be necessary to prompt user to set up a task. This is the essence of a Gantt chart without having to vest myself in a whole new level of planning software. You're a fairly sophisticated planning tool, so I thought you might have this because it's not all that complicated, & the need seems self-evident to me. Anyway I'm here because i need this, & I doubt you'll be able to produce it within my free week. If you think you can deliver within a reasonable time, I'd stick around. Let me know, please.

I think it would be very useful to be able to make tasks that are hidden from my list of tasks and notifications until the completion of a different task or tasks. This could also be accomplished if subtasks were more visible on the home screen and had independent notifications.

Example: I want to make a task to fix my dining table. However, since I know that I don't currently have the supplies to do the repair, I might want to have a reminder to buy the repair materials and also a reminder to ask my sister how she did a similar repair before I get the reminder to actually fix the table. There is no point in me getting the reminder to fix the table until I finished the two earlier steps, since it's not an actionable item until then.

Make Tasks have dependency on sub tasks, so that tasks can be marked complete only after subtasks are completed

How has this not got more votes? Maybe there is a duplicate suggestion out there, but this is a super powerful feature idea and if I found any other task manager that does this, I would switch in an instant.

Having the ability to silence alerts for tasks that have not had their pre-requisites met would reduce my daily "Moment" items by 50%.

I dont think we're asking for advanced PM features here, just a simple way to prevent useless alerts and reduce alert fatigue

Completing a task should be able to cause a personalized reaction in the app. E.g. If you completed task 1, task 2 is automatically added to the category "tomorrow"
Or: when I complete task 1, remind me to do task 2

A main task can be marked as done, only if the subtasks are marked as done as well ... or you get a pop-up or something, telling you the there are still some subtasks open.
Especially helpful for the calender.

If all of the subtasks of a task are marked as complete, the task itself should be marked as completed automatically (bonus: optiion to toggle this feature on/off)

If only I could give all of my votes to this suggestion.

I do not speak English very well I hope to explain the idea well. It would be important to add to the application, a follow-up to objectives, that is, enter a goal equal to 100% and be able to include tasks that once completed these tasks, will help to meet the objective

When you realize you can do two tasks right after another and you don't want to forget about the next task, a chaining option will be useful. I imagine it as one big block of tasks which can be moved as a whole and numbering inside this block shows the sequence of completeing tha tasks.

Giving priority to certain tassks is possible and I appreciate that. However, sometimes because I dont see the dependencies between one task and the other, I find myself doing things with less efficiency. creating dependencies helps to organize my workflow better.

This is great idea! It just pushes the time management with this app to the whole new level. You can basically line up a sequence of tasks, related to a particular project, and then just follow easily. I definitely need this!

Add a feature that allows for creation of a list of tasks where some must be marked as completed before others

All tasks could have a 'next step' task and if you finish this next step it should ask for the next step of it's task/project. With this feature the program should better fit systems like David Allen's Get Things Done book. Hope you like it! :)

I would really appreciate such a feature. It would bring Any.do to a whole new level!

If someone checks all of the subtasks of a main task, it means that the main task is completed, so it should be automaticly marked as completed
