When working with documentation systems it would be
neat to have horizontal folding (for commands) i.e.
iff a comment spans only part of a line it should be
possible to have it folded (and replaced by a special
symbol, like a circle) i.e. for C++
void my_func(int p1 /**a para*/, int p2 /**an other
void my_func(int p1 °, int p2 °)
expansion could be via click, shortkey for expand at
cursor or fully expandf a row
what do you think of this?
