Hi Michael,

Regarding your speed control utility...

I personally think a Windows style point and click interface would suit many
(e.g. head-tracker users, eye tracker users, trackball users, touch screen
and so on). Bear in mind that triggering lots of clicks can be very
laborious for users - especially if they're using a dwell clicker. Equally -
not all can trigger a held mouse-click. Take a look at "Great Britain
Limited" http://demonews.com/download-3115.html for an example of
problematic control for adjusting parameters through dwell clicking.

I would also like to see a switch accessible menu for one or two switches -
and a joystick accessible menu. All reconfigurable if possible.


On top of this - a switch accessible menu would be great. Some switch users
can take control over the mouse pointer - but it can be quite laborious.
Scan and select is faster. It's critical to try to avoid clashing with the
game controls. Calling and exiting this software will need some thought for

There again - if you could build a menu based profile system - where you can
select a specific speed then have your utility start up the game you might
solve this problem (thinking of those using a single switch or two
