If you merge a couple layers while working with our online image editor, you may occasionally find afterwards that not all Alphas, Blend Modes, or Layer Filters look as expected. One solution to this problem is to use a Phoenix Smart Layer to create a group of layers that will retain all of their attributes, along with their editability (is that even a word?). Basically, Smart Layers are external files that act as a single layer within the original. All the elements are isolated so they're safe from accidental edits. Smart layers are a great way to organize files, protect layers, or add elements from our vector or effects editors.
