Line height and collaps/expand in Behavior editor

I would like to be able to reduce the line height in the Behaviour Editor to make room for more. I find my self scrolling a lot, and I don’t need that much white space between the lines of “code”.

The ability to collapse and expand parts of the code would also be appreciated.

In my recent prototype I have 177 lines in the editor for a specific page and being able to collapse parts of them would be nice. However, my first request about the line height is the most important one.
