Project filter UI

Currently for projects a, b.c, b.c.d, we might see simply the following:

a         3
b.c   (2) 7
b.c.d     5

The implication here is that there are 3 tasks with project:a, 2 tasks with project:b.c, and 5 tasks with project:b.c.d.

Note the visual cue that b.c is a non-leaf project, because of the second count in parentheses.

If we tap the non-leaf project b.c, it folds the display as the following:

a         3
b.c   (2) 7

The Taskwarrior project displays this as follows:

a         3
b         7
  c       7
    d     5

I've considered some other designs for displaying projects.

TaskwarriorC2 abbreviated project names somehow.

I could make the parent project segment of a project string dim or grey, to indicate the parent, but I want to avoid visual cues that rely on this sort of formatting.
