[idea]: Mindmapping-like interface to taskwarrior

Sometimes filters are not enough and a huge list of tasks can be a bit... Overwhelming on TW and tasksched even with the search bar for filters which is pure love <3 (kudos to past me on that :-D).

I've been thinking about a way to have $something that makes things easier to navigate, an option would be a visual mindmapping-like interface.

Functionality wise, it would be absolutely necessary to:
* Manipulate "blocks / depends" for tasks
* Create tasks on-the-fly
* Use the search bar for filters
* "Zoom in and out"

It'd also be nice to:
* Be able to schedule things from this interface
* Be able to close tasks (should be added to tasksched's interface too :-D)
* Have helper buttons for the filters based on the task / project.

There are some things that interact here:
* Hierarchy
* Task inter-Dependency

And different use-cases:
* General overview (macro-managing/planning)
* Planning (micro-managing/planning)

I think Dependency maps quite well to "blocks / depends" in TW and Hierarchy can be inferred from it: in the end tasks behave like a directed graph without cycles (I think! :-D am I wrong?).
To infer hierarchy from dependencies, we can think of hierarchy being inverse to the length of the longest chain of blocked tasks and dynamically be mapped to 3-4 levels. (e.g.: 0 tasks blocked by T means T has hierarchy 1 / top, longest chain of tasks blocked by T with length: 1-2 mean hierarchy is 2 / mid, with length 3-5 would have hierarchy 3/low and with length 6+ hierarchy 4/marginal).
Likely "Hierarchy" should be tunable as a TW UDA.

In a "General overview" mode, we'd emphasise tasks with a high hierarchy and in "Planning" mode items with a low hierarchy.

I think TW's priority wouldn't be fit for this "Hierarchy" concept, since that's more of an urgency measure which is correlated but not a direct mapping in most cases.

Does this at least *kinda* make sense? Is it worth exploring?

Does it sound like Too Much Work (tm) and maybe it's just better to use [FreeMind](http://freemind.sourceforge.net/wiki/index.php/Main_Page)?
