Woopsi Ant512, a homebrew developer specializing in Nintendo DS applications is trying to break the groundwork for other homebrew coders with the Woopsi homebrew, which aims to create a simple windowing system that programmers can use for their own applications.
Written in C++, Woopsi v0.24 is loosely based on the Commodore Amiga's "Intuition" windowing system. The GUI itself works everything in a "screen" environment, and the look and feel of the system intentionally resembles the old Amiga System.
The developer did not intend the application to be a complete desktop environment, nor was it created as a DS version of GNOME, KDE or Windows Explorer. It was instead developed as a basis for other programmers to build their own window and gadget-based interfaces for the handheld system.
The latest version still has minor issues with the layouting, but Ant512 assures everyone that these minor adjustments will be implemented in later updates. Here's a list of the fixes and new features included with Woopsi v0.24:
Tidied up a lot of the code.
Gadget deletion queue now handled solely in the VBL events.
Optimised TextWriter by preventing it from drawing empty glyphs.
Changed TextWriter into a static class.
Optimised TextViewer so that it uses much less memory.
Text font and glyph font now sent around hierarchy instead of each gadget creating their own font.

Removed 8-bit code from Bitmap class.

PIXELMAN From Sylus101:Sprite Designing/Testing/Creating/Animating On the GO!Just so it's clear and the purpose of the app isn't in question (as I think it might be) this is intended to be a developers helper in designing/modifying sprites, particularly for use with PALib, but since there is a binary export now I'm gathering they could be used with any dev platform (not like there are many others
