pgAdmin4, how to customize sql panel font size

Hi,

i installed pgAdmin4 Beta 4 on OSX 10.10.5
thanks for the rewrite, it looks really good :)

one little thing, i am not sure if this only on my mac, but for my taste the font size of the SQL panel is a bit too
big,approx 16pt 
is there a way to customize it? I would prefer the same font size as the tab-title.
i looked in the preferences but did not found anything font related.

here is a screenshot for reference:
