i would like to scale down the tool icons. is there a way to do this without replacing the bitmaps? i want to retain the shelf without taking too much space.

i have tried looking at the MELscripts in the preferences ... there are height and width settings for each button. i edited them and they keep returning back to 34. are these the right params? (sorry i am a maya newbie i dont know any MEL)

or perhaps there are downloadable alternative icons somewhere?

thanks in advance.
