LogBook 1.2.1 patch release is now available on googlecode now. The release addresses quite a few bugs and feature requests. The list of patches can be found here.
We are also discussing features for LogBook 1.3 at the Google group for the project. If you have a feature you would like to see added or contribute, join the conversation here. Like Mat said in a previous thread there, the importance of a feature is only as much as the conversation around it.
There are some interesting discussions I have had around LogBook with a couple of folk within Comcast Interactive Media where I work. For example, one of the things we have had to deal with is QA bugs that we cannot reproduce. Running LogBook in the background on QA machines and looking at the logs generated would be an interesting idea to implement, thus making LogBook a part of the QA cycle. The biggest thing that needs is a notion of a session in LogBook which is something we dont have right now. I guess that could be a part of 1.3 or 1.4. Other ideas are welcome.
If you have any code around debugging Flex applications that you would like to contribute to LogBook, do let me know as well.
