It depends mostly on users response. If I see that a good number of people is interested in the project further features could be added.
Anyway, I plan to debug and stabilize the current set of features, leading to a 1.0.0 version. Another point of improvement could be portability. Right now it only has been tested on Linux. I plan to test it with Solaris/gcc soon, but most other platforms should have to rely on volunteers to do the work, as I don't have any other machines to test,
