You can report bugs and requests new features. There's no guarantee that I'll implement feature requests, but you could at least give it a try.
My design philosophy with addons is quite simple:
Provide solid functionality
Make them as self explaining as possible
Allow for a certain level of customization
Support both English and German language
Have a (in my eyes) candy user interface
Writing addons takes a huge amount of time. In case you like my addons you're always free to do a donation while downloading the latest version. I'll promise to make sure that I'll think about the donator while having a beer on his costs
