I've not posted recently because my current job involves Drupal 6 so I've done virtually no D7 work for a while. However I do have a new set of modules for developers coming soon which will be in both D6 and D7 varieties.
Essentially it's a system that does a similar job to CTools plugins but is lightweight and standalone. It's very good for de-coupling dependent custom modules, essentially very simple but very versatile.
There's a core module that provides the API (a very small module indeed) and then some other modules that demonstrate how to use it and provide handy facilities at the same time.
Hopefully I'll have that out by Christmas. I'm also happy to say that my field_extract module is doing very nicely in the module usage charts currently standing at 99 sites.
