you are absolutely right.
so i'll close i#98.

Great!
We should allow users to use environment variables through '$'. And we
could also address to DITrack variables with '%'.
But if '%' already means that it's DITrack-provided value, why do you use
prefix 'DT'. Why not simply '%USER':
my: Status=open,Owned-by=%USER

Or may be to simplify parsing we should use both-side-percent-symbol:
my: Status=open,Owned-by=%DTUSER%
?

Vlad, will you open new issue on me about using DITrack-provided values?
