I made a nudge button !
Setting Nudge steps for Meters and Millimeters
Discovered some bugs and weird issues:
-
When editing the Macro or the image, Rhino crashes when i hit “apply”
-
I can get the button edit to work, by deleting the old one, and make a new one, by filling in the edited content in the Button form.
-
BUT … now the _Direction interchanges between _Cplane and _View, when i either left click or right click
So the button is kinda useless, because i can not really be sure what direction is set, and I would have to open Settings>ModelingAids>Nudge and make sure the Nudge Direction is set to “Use View Axes” and then it would change again, next time i use the button…
Please check this bug out, thanks 
Here are the Macros, (Thanks to @Helvetosaur )
You can set your own preferred steps in the macro
(well , maybe not, if the bug is still on 
)
I have tried to upload a nice SVG icon, but apparently its not possible to show SVG files ?
