[FR] Highlight selected code cell

[jkrumbiegel]

It would be great if the currently active code cell, between ## or #-- lines, was highlighted in a color that lies between the selected line color and background color. It's not very salient when moving between code cells with alt + down / up what code is contained in the current cell. You have to instead visually scan the code until you find the next separator. Hopefully this feature would require only a small css modification.
