I think GLBasic is a perfect language for beginners and people that needs to create a game/program without fight with complex languages or tools.
It is pretty because... Hey! It is BASIC! And it compiles for iOS, Android, Windows, Mac and GNU/Linux!!! It is multiplatform and you don't need to change your code!!!
I'm sure this kind of product is very hard to mantain, because of that, may be that the best roadmap could be to consolidate certain main platforms, before add new platforms to the language... the work of Gernot is impressive, but he is an only one programmer and now users/programmers have new needs that comes with each change in the OS/platforms/devices after each of these updates from big companies.
The capability of GLBasic to be extended through wrappers or inline code makes of GLBasic a real jewel for coders, but I think that the creation of wrappers to obtain certain main capabilities like Game Center, social, or iADs are starting to became more and more complex, considering the speed of changes from market, and big companies.
Sometimes you need functions that should be integrated into the language/compiler itself, if you need to fix a bug or cover a new function included (I refer, for example, to iOS 6... iOS 7... Apple and its policies and changes, etc.) and that could certainly be a "monster work" for an only one man... And people may turn crazy or impatient when this kind of problems avoid a programmer to finish/correct/publish an app.
I would not like to see GLBasic die slowly like other projects because the man behind GLB could not update the language as the tech evolves.
How to solve problems?
May be that a solution could be to open a little part of the source code that GLBasic uses to embed the OpenGL view, to let this community (us) to collaborate extending and fixing faster certain not trivial bugs or adding new features... If the platforms where this could be possible.
This is a suggestion that Gernot could think about... I hope to not hurt to Gernot or anyone because of explain my personal opinion.
