Functions

The script has two main buttons: TextBG and TextLINE

To apply the effects, simply select the (text) layer(s) in your composition and hit the corresponding button. The script will create and adapt a shape layer, which is parented to your previously selected (text) layer.

Parenting

Once created you can change the parent of the TextBG or TextLINE shape layer at any time. The layer will then jump and change dynamicly to its new parent.

Not just text layers

The usage of the effect layers is not limited to only text layers. Any layer which has a bounding box (which is basically every layer except cameras and light since they don't have dimensions) can work as a parent layer for the effect layers.
