Add `pct:` custom tag (or something similar) to keep track of progress about sleek

While waiting for an opinion from the developer, I share my working method, maybe it can be an inspiration for you.

I created some specific contexts that identify the status of the task. In my case it is not important to keep track of the real completion percentage. Example: task started, to be reviewed or in waiting status ( @status_going, @status_review, @status_waiting ).

I realize this isn't exactly what you want to do but it might be a temporary work around.

@mimmori your solution is actually rather similar to what I have been using. When I have many contexts, it is not so immediately visible, though...
