This is the current list of proof of concepts that need some polishing or that I've just done the research for:
- bluetooth handsfree calls (audio crackles)
- bluetooth address book sync (uses similar protocols to the handsfree but haven't gotten it working yet)
- GUI framework for scalable (SVG) and skinnable buttons (mostly working, needs some text rendering and layout tweaks)
- GUI framework for pretty popup indicators like info bubbles or the translucent volume control widget on macs (basics are working, needs some layout tweaks and a built-in timer to hide after a set period of time)
- actually using the new GUI framework features from the app
- GUI for cell phone that integrates the bluetooth backend stuff
GUI for NetworkManager wireless selection
- plugin architecture for frontend so that it's easy to add new functionality (already using a basic form of it but it could be a lot better)
- switch to new mapping framework, add routing, redo the GPS plugin (pretty massive effort relative to the rest)
- hooks to tie voice recognition to GUI and plugin logic
There's a ton more but I think that list is a good start.
