"ECS":
- IDE interface that supports DMA
- SFS ported to 68000
- Instant loading of icons (proper caching, or even saved, clickable bitmaps)
- extra non-bitplane hires modes (Indivision ECS-like hardware)
- above preferably accelerated, so there is any chance of a fast antialiased font engine or 3D (dreaming...)
"AGA":
- same as above (SFS already works ofc), but an Indivision with similar non-bitplane modes to the ECS version and software 'accelerated' font and 3D might suffice. Won't help the non-accelerated A1200 owners, though.
