Latest weeks I've been working a lot on improving the WPF PropertyGrid.
There are improvements in lot of areas:
- Appearance completely customizable through XAML
- Advanced color editor (Photoshop style: HSB/RGB model with Alpha)
- Advanced matrix editor (includes matrix tranposition, matrix inversion, translation, rotation)
- Dynamic filtering (textbox at the top) with nice animation effects (collapsing/expanding)
- Animations everywhere to give user a good visual feedback
- Lazy tree evaluation (allow recursivity)

Here is the result (binaries for the demo are attached):

I'm seriously considering double licensing it for commercial use (while still keeping it under GPL for opensource projects). What do you think about it ?
