OH my desire for transparency is nothing interesting, it's just easier when working with multiple layers to have stuff like linework and shading all separate. y'know, so the lines are just what you see and that layer's transparent in the parts where the lines aren't. it makes moving stuff around and adding new layers in a lot simpler. (really I need it more for concepting where I'm constantly hodgepodging things than comics)

(ryan estrada's speed comicing piece mentions a quick workaround (using the darken layer mode), buuuut that becomes a hassle if you're doing stuff more complex than the coloring he describes. you can always "fix" lineart like that through the use of the alpha channel in PS (I can explain how if anyone cares), but it's still slower than just having transparency built in. (in sai you just use luminance to transparency ofc))
