A tailor-made file that opens as the start-up file in Illustrator 30 on Sequoia
In the old days, I'd create a file customized to my preferred document setup, color, layout, specifications, etc. and have it come up on Command+N and Command+Option+N. It wasn't an AIT, just a standard file placed deep in Illustrator's many files and folders. Maybe Presets, maybe Profiles, or somesuch.
Would someone be so kind as to tell me where I'd put such a custom-made file in Illustrator 30?
