Dear santa ...
1. I need native looks as themes. Some users like OSX on Windows etc
2. I need a fully customizable look and feel. Most customers want company or product look and feel with stunning graphics these days.
3. We need to compete with web developers in graphics and performance.
4. In fact, why can't my desc-top app become a web if I want to.
5. I need a GUI that can use GPU's without me noticing. I have no use for GPU's that are idle and even rPI have GPU.
6. I would like to code in a standard like LCL and not know about these things.
7. It must be lightning fast on my rPI...
I could continue
