Installation:
Copy the .ms file to the scripts\startup folder and restart Max. The modifier is found in the modifier list.

Tips:
($.modifiers[1].rollouts())[1]
Assuming that PEN_attributeHolder is the first modifier in the stack this will return the Presets rollout. You can use createDialog to open it as a floating window. PEN_AttributeHolder can't be displayed in the modifier stack at the same time because the rollout can't be created twice.

Name: Name of a new preset to be created.
Add: Set the spinners and sliders to the value you want to create a preset for, type a name in the Name field and then press Add. A new preset will show up in the presets list.
Delete Selected Preset: Select the preset from the Presets list and press Delete.
Delete All Presets: Deletes all the presets for the modifier.
Save: Saves all the presets to a text file.
Load: Loads presets from a text file over writing the originals. Note: This works based on the order of the CA's on the modifier and not by their names.
Merge: Merges presets from a text file with existing presets. Note: It is possible to create duplicate names with different settings.
Presets: This is a list of all presets and when one is chosen from the list all the attributes will be updated to the preset value.

Ramp: This is a new feature in v2.05, it allows for the values of the presets to be ramped up and used at any point. The green button is a toggle for this feature incase you want to have it work in an absolute fashion. Select a preset and ramp the slider from 0 to 100 to get a gradual result for the preset.

Key All: Keys all attributes added to the modifier.
Reset All: Resets all attributes on the modifier to a value of 0.
Copy: Copies the existing values of the CA's to the buffer.
Paste: Pastes the buffer back to the CA's. This is great for copying and pasting a pose from one hand to another.
