I am seeing flash on my HTC One (Max) when using code from that GitHub repo. That's enough of a reason to not use it.
For stock launcher, it works, but I don't like the new permissions.
Facebook? Maybe you could call Mr. Zukerberg for me and ask him to share the code?
Many people talk about uninstalling Facebook because of too many permissions, but I guess very few do (esp. when it's baked into the ROM).
Don't think I'm in the same boat with my app.
In the end, here is what we have now:
- App's own wigdets
- Apex Launcher
- Nova Launcher
- Samsung devices
- LG devices
- Sony devices
Personally, I think that's pretty good coverage.
