I think Sunsama is missing a really neat visual/UX representation here: I love the "drag tasks around your worktime" idea that Sunsama is based on, and I would love if incomplete dependencies get pulled along when I drag a task that depends on it. E.g. I've scheduled task X for Tuesday, but I decide it'd be great to get it finished sooner and so I drag it to Monday. I would love if all the tasks it depends on also get pulled to Monday in front of it, so it's clear to me, "oh right, I can't actually do X unless I do Y first". If Task X is scheduled for 2pm and I try to drag it before Task Y on my list for the day, Task Y should also be dragged along so that the dependencies are always respected. Similarly, dragging task X out of the backlog into my schedule should pull in its prerequisites as well.

I’d like to request the ability to create task dependencies in Sunsama. Specifically, the option to mark one task as dependent on the completion of another task.

Given the fact, that in tools like Asana and Clickup there are a lot of big projects with a lot of task dependencies, it would be great if there was an option to only display tasks that don't have a dependency (aren't blocked by another task). 
Right now, when opening the Asana tab, I see hundreds of tasks  🧐

Task dependencies

Task dependencies are dependencies between tasks that determine in which order and how they must be executed. This means that one task can have a dependency on another, which means that it cannot start until another task has been completed. Such dependencies are crucial in project management, as they help to establish the schedule and sequence of work.
There are different types of dependencies between tasks:
Finish-to-Start (FS) - task B cannot start until task A is complete (the most common dependency). 
Start-to-Start (SS) - task B cannot start until task A has started. 
Finish-to-Finish (FF) - task B cannot finish until task A is complete. 
Start-to-Finish (SF) - task B cannot finish until task
Of just simple task dependencies like Finish-to-Start (FS).

Add task dependency in planning
Mike Le Galloudec
I'd like to be able to add a dependency of one task on another, so that when tasks are scheduled or re-scheduled one will always be after the other. If I try to schedule the dependant task before its counterpart, I'd like to be warned.

I'm struggling without task dependencies. Sure I could paint my rental, but it really only should be done after the windows and trim are replaced. This has been a huge blocker to full adoption of Sunsama for me.

Chain tasks

Sometimes I have tasks with dependencies (can't fix the machine until I have the part) even though I know the steps ahead of time. It would be nice to not have to manually keep track of the order of tasks like this.

Contingent Tasks

It would be great if there could be contingent tasks. When I check off a task, one that was dependent on it appeared on my list.
