Before You Die
Concept
Task organization with dependency chains. Kinda like google buganizer or jira (task management applications) but simple and for a todo list.
Example
Imagine you need to create a bank account and you're immigrating to a new country.
You have a dependency graph of things to do in order to achieve that goal like so:
Make a Government ID -> Make a Cell Phone Number ----
\
\
Aquire Proof of employment ------------------------> Make a Bank Account
The creation of a bank account is somewhat contrived, but perhaps planning a vacation is more your style.
You can imagine you need to select dates that match everyone's schedule and events you wish to attend, secure a hotel
and flight, purchase various tickets, arrange for visas etc in some particular order.
Rather than represent this chain of events as a flat list (or even a simple list with indented items), you can represent it as this kind of "graph" where one task points to the tasks it blocks (one or more).
Now you can have a special list that only shows you the tasks that are currently not blocked so you can get things done without the stress of all the things you need to do bogging you down.
Just open up the list and start addressing things you can do right now without the overhead
