So you started your own standalone software project from scratch, instead of working with an existing codebase to fix issues… 
Well… see “Things You Should Never Do, Part I – Joel on Software”.
In the meantime, in the span of a couple of months, the Tiki project implemented a preliminary kanban feature (see also the separate thread I posted about that, to keep things short here). In Tiki’s case, I trust it will still be around many years down the road, because it does have a large team of people maintaining the whole thing.
