I've been working away like crazy on PBooks lately, and I'm closing in on a release of 0.07.
I'm not relying on the trac roadmap right now, as I think the planning can get a little bit ahead of the functionality with software, so I'm using the software and reviewing the code to let my mind analyze everything. In this process, I've been adding a lot of source code comments and its already helping me be more productive when I need to dive into a file and get my bearings.
Its funny, because adding a lot of comments makes the file seem messy, but its much easier to understand. The more I add comments, the more comfortable I'll get with them and I'm sure I'll find my own style.
There isn't anything groundbreaking in changes from 0.06, but several obscure bugs have been squashed, as well as a lot of minor but important interface improvements. The code base is also a lot more consistent.
I've also been updating and cleaning up the tests a lot. After the addition of a few business processes to PBooks, I realized the need to keep the tests organized and consistent, so we can keep up with testing new functionality as it unfolds.
Which reminds me, one of the remaining tasks before a 0.07 release is the addition of Purchase Orders to PBooks. So I'll get started on that now!
