* Different coloured backgrounds
* Displaying sprite objects
* 'Think' code for each object, so you can set up animations, movements, etc. by specifying the time you want them to occur
* Collision detection, either finding out what is under a single point or what is colliding with an object

Soon I'll have mouse click events being transferred to objects, so if your backdrop has some animated creatures of some sort then you can click on them to pick them up, scare them off, etc.

I'll also sort out private memory space for each object, extra effects you can apply to the objects (They are being plotted as icons, so effects could include being selected, greyed out, text, etc.), some easy to use method of layering the objects, functions to work out how large an object is based around its sprite (The current system draws things using screen pixels, but the WIMP works in OS units and its icon plotter will attempt to rescale sprites depending on their DPI), and an options window.
