Sub-tasks (nested)

[kem]

Hi!
I'm trying out Tudumo, and so far it's by far the closest to my dream
app.
I don't follow GTD guidelines-I've read the book, apply some of the
basic concepts, but found I work better with a slightly different
structure, but tudumo seems to adapt quite well to my needs.

The only thing I'm missing- subtasks, or nested tasks (or nested
headings). I've read discussions about combining tags and headers to
apply the same kind of structure, but for me this is not very
convenient.

I want to open up tudumo and be able to see (for example):

Client Projects
-------------------------------
-Project1
--Do Something (tags: design, computer)
--Do Something else after that (tags: admin, phone)
--One more thing (tags: programming, computer)
-Project2
--etc

I could use Project1 and Project2 as tags, but then getting a per-
project overview would be one click away, and i could only see one
project at a time, as opposed to getting the outline I mentioned.

Hopefully my suggestion is useful :)
