1) Donations are given without return consideration. Nobody should expect anything in return for a donation. If tgalal so chooses to provide an update as to what's going on with the project, good, otherwise, don't go about with the idea that updates are expected.

2) Putting source on github (or similar) - for a project that is obviously as popular as this, I'd think this would at best improve development times by a hair... and cause other problems. Every Tom, Dick, and Harry that has an N9 and has opened the command prompt before will assume that they have the knowhow to compile/install the source; and when the vast majority fail, this thread will then be populated by that vast majority expecting support/a .deb file for each nightly release/etc.

IMHO, the project is best left as is. The project is tgalal's, the updates should come on his terms, and assuming he does need/want help with the code, he can easily ask for it.
