Welcome, young wiggler!
Motion designers shouldn't rely on code to do basic shit.

For a 1:1 live preview, set your viewport zoom to 100% (Keyboard shortcut: "/")
The live preview adjusts itself to the type of the selected properties
Adjust the panel size to fit your workspace
Use the loop button to make a looping wiggle. Set the duration of the loop to when you want wiggle to repeat itself
Use the dimensions button to limit the wiggle to a specific axis (X, Y, Z)

Apply Wiggle to multiple selected properties at once
Load existing expressions straight into the Wiggle
Set the sensitivity of the sliders using Right Click > Edit Value, and set a floating-point value (0.0) or an integer (0)
Go beyond the default range of any slider using Right Click > Edit Value, and set the value you wish to use
The Good Boy Ninja wishes you good luck!If you enjoy using Wiggle, please consider buying one of the other tools I have made for you. I am putting a lot of effort and love into them, each purchase allows me to create more tools such as this one.
Have fun wiggling!
