Limitation

Action Constraint Rotation Limitation

Blender’s Action Constraint have a limitation for Rotation, You can only have controlling value clamp betweeen -180 and 180

To compensate for this limitation, the addon will wrap the value between -180 and 180, that means if your controller value is 185, it will be wrap into -5 when keying the action

Limitation Bypass using Drivers and intermediate Bone

To Bypass this limit, I suggest to use only location for this addon on a intermediate bone, and then a rotation channel as driver to drive the intermediate bone, you can then hide the intermediate bone away to not clutter your scene

Object Origin Problem

If You are using set driven key for Objects instead of bone, you will notice that the origin of the object is wierd, you can either live with it, or temporarily disable your constraint when you are keying, set driven key works regardless if the constraint is on or not

This limitation is only for object, Bone does not have this limitation

World Space Controller Slider

Unfortunately, if your controller is in World Space, you will not be able to use the slider in the UI List
