It would be a guide for radial line, concentric cirlces, etc. Special Rulers, similar to those found in Clip Studio Paint.
These could be tabs or something similar. However, could you make something like Favorite 1, Favorite 2, etc.? The main reason is so if your working on a paining and then you need to work on an inked illustration, you can have different Favorite sets for each approach. It's SO easy and makes the creative process much easier. I love how you can save a brush as a favorite. With that, I do have few suggestions to hopefully be implemented in 3.0. This should be just as big as Procreate.Thank you for it. Let me say this again, this is the most underrated app on the iPad, hands down.
