Sure, both OT code and hierarchy is simple if font is lightweight, but it gets confusing real fast when there's locl, case, calt, liga, dlig, smcp, c2sc, swsh, frac, ss01-07, sinf/sups/subs, numr/dnom, lnum/onum, pnum/tnum etc. to work with.

I know that everyone's have different methods and it varies from font to font, but what's your usual strategy? Do you put most common features at the top or vice versa? The ones that affect the most glyphs?

    I mainly look out for possible interactions when multiple features are applied. For instance, I put smcp before liga. If I didn't, I'd have to figure out a way to transform fi, fl, ffi, ffl, etc. into small caps in the smcp feature. Similarly, I place frac and sinf/sups/subs before figure style transformations.
