I still think that mobile development is nothing a hobby developer should pursue, your game will just get lost in a pool of a million other games without massive marketing or luck beyond description. The regular mobile game consumer does not actively search for indie games or whatever and neither wants to pay more than a few cents per title.

Personally I just want to have a solid and easy to use PC engine/ toolset. Linux and Mac support would be nice to have as an "export option" but a development for multiple platforms is not that feasible for a single hobby dev anyway. I'd just like to see a new WED, some new features every now and then and bug fixes but any kind of update is good news.

I think the toolset and general workflow of GS3d needs most work. More macro's, small sed templates for complicated stuff (small stuff so it doesn't get outdated fast), making that ctrl+space sed windows bigger. More and updated shaders, including better shadow shaders and terrain shaders. Better debugging tools. Easy to set-up windows dialogues (would be nice as extra flags/functions for panels). More modern version of and less buggy MED. New WED.

Models being able to split the world in manageable chunks just like blocks can would be nice too so blocks are not needed for that anymore. And other stuff to increase performance.

Linux and Mac support is nice for people who want to sell their stuff (+ ~10-15% potential sales ?). I don't know how much time it costs to implement though. Android support would also nice but more for fun stuff than serious stuff I must admit.

Small features are always welcome too and they can be faster implemented by the devs so that's a plus.
