Create a roadmap

[balt-dev]

I'd honestly like to see a roadmap of the project, so that I know what I can expect to be implemented soon, and what might have to wait a bit.

I honestly have nothing really planned out other than a big fix the memory leak. Features are mostly added on a whim over the course of 1-2 days, and I don't really dedicate a lot of time on the project consistently.
