Function Request - Modulo Operation

@DJ, For the next release, can you please add: 1) Modulus Function e.g. Mod( Number1, Number2 ) OR 2) Modulus operator e.g. Number1 % Number2 I know you can use plugins to add custom functions, but they don't work on mobile applications. Modulus is so versatile and useful deserves a place in EZ-Script. Simple examples: 1) $counter=0 :loop #do...

It occured to me that it might be fun to build something that showed the relationship of items. I could do this with a spreadsheet but is it possible to use whats built into ARC? Example: Show all the places that...

To fix it I have to open the dynamixel plugin and uncheck the servos, then enable them again then save it. After i return to the layout...
