Enabling users to work with legend will be a good step forward. I
think we could create a QgsLegendInterface class available in gui
library that would allow manipulation with layers and groups in legend
widget:
- add / remove a group
- add / remove layer to/from a group
- list contents of legend or of one group
- modify layer / group visibility in canvas
- more...

But as always, there has to be someone to create such interface and do
the connection with legend classes - your patches are welcome!
