I have recorded my first macro "BlueSketch" (attached below). It is doing this: if you import a scanned sketch, graphite on paper like mine, it is sometimes hard to use the digital tools to trace it. It can be hard to see what is sketch and what is digital linework. The macro adds a new raster layer on top of the sketch, fills it with blue, turns the layer into Colour mode, and adds new empty top layer for your linework / inking. Just like the layer function in ClipStudio, where I use it all the time. Put the macro in the Library and the BlueSketch is instantly done. I hope it works for you the same way it does for me.
