Taken inspiration from NT Productions , I put this little dockable script together for your use. Imagine needing to resize text layers quickly and they stay that size bypassing the font pixel size. Add controls to the layer to change after the the fact with sliders or apply just an expression to the layer. Control the Width or the Height…or both. Select one text layer or all the text layer, it doesn’t matter, this little bad boy will save you time.
