Here's little bit of history.
Currently, Zeppelin has 3 Looknfeels. 'default', 'simple' and 'report'. But
before the looknfeel feature, there were only single style, and that was
'simple'. 'default' was introduced as a alternative to 'simple', based on
feedbacks
* Hard to distinguish Paragraphs -> gray background
* Hard to find buttons -> controls always shown
Therefore 'default' was intended to show controls always, while 'simple'
show only on hover mouse.
It could be challenging, but what do you think make it aware contents
length of 1st line and hide (or make it almost transparent) control only when
there're text underneath, and show as a normal on mouse hover? Do you think
it's a good idea?
