Hi Der Vogel,
sorry for this late answer, I'm deeply involved in developing of "WiFi configuration support" for the next upcoming release.
First of all, thanks for your suggestions and your offer of collaboration.
Let me answer your questions, point by point:
- Translation of the GUI and the docs. I volunteer for the French translation
This feature is planned for version
0.4, in that release will also add the
"color scheme selection" feature.
Publish versions following semantic versioning. Please reserve the beta flag for testing versions. What is the point to publish only beta version while increasing the version number? I think you have already achieve a great work, and it is a pity to do not highlight it by releasing a version 1.0. Two many projects are stuck with this zero prefix although they are already fully functional. Why not the following: 0.3 should be 1.0 beta and 0.4, 1.0. It makes sense as you announced lots of improvements in the forum and in the blog.
Our "vison" on version numbering, is a sort of "breadcrumbs path" to 1.0 version.
In our mind 1.0 should contain a full "key features" set, like
playback sync between multiple players,
hi quality equalizer,
resampling management,
UI translation,
color scheme selection, and many more. Each "zero point" release, is intended to introduce two or three of these key features at a time.
The BETA tag is there because, after only two releases, we haven't achieved the perfect stability of all the features in
all different operativity conditions. I think that after v0.3, we will introduce the first STABLE release (probably v0.4 will be the first stable release). Do not misunderstand me, v0.3-alpha is now absolutely more "stable" than the current v0.2, but when I think at a "stable" release I mean absolutely "rock solid".
Respect the terms of the license GPL 3 you choose. As other users pointed out, a public repository should solve the access to the code (and then enable users contribution?). I hope the competition with Volumio is not the reason for this oversight 
There is no competition with Volumio, but only different "visions" of project statement and development.
The only reason why the current release is not public, is that we decided to do a complete rewrite of the foundations of the code. Only now, after more than
300 commits, the code is ready to be published in its entirety. From now on, the development will be fully public, and absolutely open to your contribution.
We consider this a new "starting point". I agree with you, this deserves a 1.0 version, but we decided not to break the continuity of the line of development in order to not create confusion.
Our project is absolutely Open Source and always will be. The source code of the current release, is available on our
GitHub repository.
Your offer of contribute is well accepted, so stay tuned for the next upcoming release.
Regards.
Simone.
. Re: semantic versioning, this is something some of us more or less do intuitively, glad to see someone successfully IMHO organized and wrote down in a systematic fashion. And finally yes, I'd also like to see a way to share and contribute to code. If it's about competition, it should be won by the nber of contributors and the quality of their contributions; I think this project already has good foundations to keep attracting both!
