The current target is AmiKIT type environment ;-(
TrueColour GFX and ultra fast CPU/mem bus.
I have managed to persuade the developers to keep the compatibility to the classic,
but performance wise we have a problem with the colour requester, it requires enormous resources.
The main MUI backbone is roughly as fast as it was, just 020 optimized and more stable/bug fixed.
Any reports are welcomed while development is hot, so that things can be addressed before release and we would not need to complain why it's not working or something is wrong.
