May be I am ignorant about this, but could you tell me how do i switch the icon sizes to something that is provided by the theme? I have tried to search through the maze of preferences, but the only thing that i could find is "File Management" preferences and that tells me to choose between percentages. I would assume that this should be provided as additional customizations on the selected theme (since the theme knows what icon sizes it is churning out).
Does such a setting exist somewhere in the UI? If it doesn't then i think it would be nice to have it.
