PLToggle is a small app that toggles the display orientation back and forth to the rotation of your choice, without the need for the g-sensor.
The default installation includes the settings screen (available from your start menu), and the application itself, which is available via a long-hold of the call button
WVGAFIX3 allows you to change the screen resolution. It is designed mostly for devices with wide screens - 800x480 or 400x240 (Toshiba G900, SE Xperia X1, HTC Touch HD, HTC MAX 4G). So if a game or program doesn't work in wide mode you can try it in normal VGA/QVGA mode and it will probably work
KeypadLedControl By default the keypad lights turn off after 10 seconds when the device comes out of standby. This little application keeps the light on while the display is on
Mobile ScreenTester is excellent for testing your PDA''s display to quickly find dead pixels. It is simple to use and it is also a very thin application and it is FREE!
AutoLight - HTC Topaz (Diamond 2) auto adjust backlight function is a good idea with a not very good implementation. It must be said to HTC excuse that the light sensor is very noisy, especially at low light conditions.
Some alternatives do exist but are not very good or are Compact Framework application (not a very good idea for background application)

GfxBoost - activates "QTV" mode for specific surfaces. This makes for example DirectDraw display smoother and: a bit slower or significantly faster, depending on how you look at it. It also seems to have a small effect on Direct3D/OpenGL.
This is a bit tricky! If you will benchmark it the result will be lower FPS. However, it will actually appear faster
