Here's what I think should be done in no particular order:
- Build a custom reflash image
- Reflashes with latest updates (2.12.1)
- Include FBReader (replace browser/minimo for html?)
- Update registry with FBReader and SH file associations so requesting after reflash isn't necessary
- Include Feedbooks application and connection scripts(?)
- Include Automatic downloader framework and sample scripts
- Include Dropbear, but do not start on boot
- Include USB Keyboard support (*)?
- Update Busybox
- Include .lit converter
- Update contentlister to provide more than 6 files at a time
- Improve boot time and/or provide sleep or hibernate
- Multi button stylus support with eraser in scribble application
This is just off the top of my head. I can very easily build the latest reflash image.
