Better default toolbar setting

[Stefan Monov]

Eva,

> Icon buttons are quicker to use when larger.
Yes.
However, this can be partially achieved by increasing the icon size. Besides, 
the tradeoff between comfort and beauty here is worth it for me.

> I think this config option should be there.
So do I.

> It should be easier to turn it on.
Like how?

> It should be better maintained (wrt to too long action names)
Agreed.
