How to change icons size inside unity (e.g. on all programs panel). I can change launcher icons size but I don't know how to do this "inside" Unity. I made a screenshot with big icons which I'd like to change.
With "inside" I think you mean the "Dash" (of Unity).
If it's true It's not possible to change the icon size. (i.e. see this AU question)
I don't think you can change the sizes of those. At least not yet. But considering the text, are you sure you would want to?
