I think i'd like to see some more options for Controllers.. as i find it very hard to get the right sort of feel through a controller like some racing games.
Steering on a controller can either be very slow.. or very twitchy.. some more sliders.. and a much simpler layout in all of the options screens would be a nice little imrovement.
Most of the time, games that work well with arcade joypads are usually designed specifically to use a joypad and the physics within the game suffers for it to compensate for using a simplified device for steering input. Use a proper wheel on the same game and it works terribly. The opposite applies to proper simulation software. (Wheel/physics is great, joypad is really hard)
However if you haven't found it you should experiment with the analog steer smooth option in OPTIONS >> MISC. It is a very powerful way to remove over twitchy joypad problems and can be used to get from both ends of the super slow / twitchy spectrum. Try leaving the ingame wheel visible so you can see what's going on with the steer smooth effects, adjust that setting and notice the wheel respond really different to your joystick as you change the value.
try Misc >> analog steer smooth to 0.95 (the highest possible value)
The higher the number the slower the wheel turns around.
(I use about 0.8 which is quite responsive, but not too twitchy for me)
