That is not fair.
First: A lot of the items in the mentioned google code lists are user suggestions. Since when is it obligatory for an (opensource) developer to follow every user suggestion before doing "something new"?
Secondly: a number of bugs are nightly builds bugs. Nightly builds are by definition alpha/beta builds. If you want stable behavior you take a release build. If you want to experience great new functionality, and also great new bugs, you volunteer for nightly builds.
Thirdly: In every piece of software bugs are released between versions or by a service-pack or the like, unless it is a real show-stopper or a security issue (and even then Microsoft's track-record is far from good).
And as Victor mentions: the IOS builds are again nightly builds, and therefore alfa/beta builds for the adventurous among us. It means that you can expect new functionality (3D mode) and absolutely a lot of new bugs. This is the approach of this project to release every night a new build. some projects do it every month, some every quarter, and some only release to a very small "beta testers" group.
Having nightly builds and trying to bring your app to a new platform means that new nightly builds are released without possibly having solved older bugs. That is how software development works.
I have been working for other projects, for one even as release manager, which had same kind of release strategies.
I do agree about the quality control. Also the stable build contains bugs that could have been avoided.
And also yes: some nightly build bugs are/seem easy solvable but take quite some time to be solved because the developers spend more time on developing then on reading the mailing lists and/or bug trackers. Is that good or bad: I think it is both.
I do have some frustrations as well about OsmAnd resulting in currently using OsmAnd for cycling and "map viewing" use and using another app for car navigation. You could take a likewise decision. I do hope that there's "light at the end of the tunnel" so I can use OsmAnd again for everything, as it is really the only "multi-purpose Swiss army knife" among the Nav apps where some of the tools are not too good or simply not good at all.
