The Color Picker of custom colors is a feature of the Chunky (Paid) version. HTML contents is a future feature and will also be limited to the paid version. Regarding the sticky menu, there are two options:
1) Stick the bar to the bottom instead of the bottom.
2) Do some custom CSS on your own to get the bar to snuggle into it. Since every site/theme/plugin with a sticky menu has a different structure it is quite difficult to make a generic way to stick a PBB to an aribtrary menu.
