Ok, this is gonna be kind of a weird one, but hear me out…
What I propose is some sort of project option that would number the flows from 0 rather than 1.
My reasoning for this is that a fairly common musical form is the theme and variations. What I would like is to be able to have the flows numbered such that they line with the variations. So, the Theme is Flow 0, Variation 1 is Flow 1, Variation N is Flow N, etc. Instead of the current Theme is Flow 1, Variation 1 is Flow 2, Variation N is Flow N+1
Basically just something to save the human a little mental bandwidth.
