How to make apps run in Full Screen ?

[UKBeast]

I want make some apps run in full screen mode to gain screen space, I can do this with hiding docks, but I do not want to hide it.

Is it possible to customize some applications to run in full screen mode without hiding dock ?

Saft plugin for safari is doing this but i do not like saft, it is not stable. Is there any other way to do it ?

Glims is nice for Safari, allows a lot different options.
