AapoRantalainen, any idea why reordering brushes by dragging does not work?
Did you consider changing the brush icon size in the brush selection window to 72 pixels?
Thanks again...

DESCRIPTION
The TSC2005 is a very low-power touch screen controller designed to work with power-sensitive, hand held applications that are based on an advanced low-voltage processor. It works with a supply voltage as low as 1.6V, which can be supplied by a single-cell battery. It contains a complete, ultralow-power, 12-bit, analog-to-digital (A/D)resistive touch screen converter, including drivers and the control logic to measur etouch pressure.
Page - 15. Variable Resolution
The TSC2005 provides either 10-bit or 12-bit resolution for the A/D converter. Lower resolution is often practical
for measuring slow changing signals such as touch pressure. Performing the conversions at lower resolution
reduces the amount of time it takes for the A/D converter to complete its conversion process, which also lowers power consumption.
Page 11. - TOUCH SCREEN OPERATION
A resistive touch screen operates by applying a voltage across a resistor network and measuring the change in
resistance at a given point on the matrix where the screen is touched by an input (stylus, pen, or finger). The
change in the resistance ratio marks the location on the touch screen.
4-WIRE TOUCH SCREEN COORDINATE PAIR MEASUREMENT
The TSC2005 supports the resistive 4-wire configurations, as shown in Figure 21. The circuit determines location
in two coordinate pair dimensions, although a third dimension can be added for measuring pressure.
A 4-wire touch screen is typically constructed as shown in Figure 21. It consists of two transparent resistive
layers separated by insulating spacers. The 4-wire touch screen panel works by applying a voltage across the vertical or horizontal resistive network. The A/D converter converts the voltage measured at the point where the panel is touched.

Wacom have 512-1024 levels of pressure sensitivity, but I don't how those compare to 10-12 bit for n900.

Well I believe in theory 10-bit resolution should give 1024 levels (2 to the power of 10) and 12-bits should give 4096 levels...
But I'd be very surprised if the N900 screen really does support that many levels.
Remember that things could be much better if we got this bug fixed:
https://bugs.maemo.org/show_bug.cgi?id=8435
I don't know if any of you have tried mypaint on diablo (n8xx) - it is pressure sensibility is a dream compared to fremantles crippled version... I believe it is a software bug not related to hardware - Mer on n8xx also had this pressure bug.
Vote for the bug now or it will be forgotten as Nokia moves towards capacitive screens!

Changed since version 14
* Added 'bug tracker' address
* Some new default keyboard shortcuts by xman
* Eraser mode like older versions by Tone
* Rotate angle is now 22,5 degrees (by Tone & CO)
When starting from application menu, it first loads 10 seconds, then disappears and dashboard is visible another 10 seconds and then it starts, color chooser on top.
