Something you may already know, but if you don't these are great timesavers while using Procreate. You can set a screen gesture to easily show the QuickMenu and Layer Select. The QuickMenu is great for storing your most used pen or action changes. Layer Select make changing layers as easy as touching the screen. If there is only one layer in the location you choose the layer will automatically change to that layer. If there are multiple layers your choices are shown on screen for you to choose. Hope this helps with your productivity.
