notes/usage.txt is out of date with respect to the insular features.

'cv03' substitutes k with kappa. Kappa, being a Greek letter, has a different approach to serifs which does not match the other insular small letters. I suggest using kra instead.

U+A765 LATIN SMALL LETTER THORN WITH STROKE always has an insular-style descender, instead of just when 'cv03' is activated.

'cv03' decomposes some precomposed characters like ī and ō, but that has no visible effect.

U+A767 LATIN SMALL LETTER THORN WITH STROKE THROUGH DESCENDER should have an insular variant.

⟨Ḋ Ḟ Ġ Ṡ Ṫ ḋ ḟ ġ ṡ ṫ⟩ are used in Irish so they should have insular variants.

Old-fashioned Latin uses a circumflex instead of a macron, so circumflexed vowels should have insular variants.

Modern editions of Latin poetry sometimes use breves on vowels, so such vowels should have insular variants.

E caudata (ę) was used in Latin and Irish so it should have an insular variant.

I suggest using the Old English variants of small/capital thorn when 'cv03'/'cv04' are enabled. They look noticeably different from the default glyphs used by most fonts, including FreeSerif, which is designed for Icelandic.

lat_Muncial does not look good compared to the other insular letters. Specifically, its terminals do not match the other insular letters’.

Old manuscripts often use combining letters to save space, so the combining Latin letters U+0363, U+0364, U+0365, U+0369, U+036C, U+036D, U+1DCA, U+1DD4, U+1DDA, U+1DDB, U+1DDC, U+1DDF, U+1DE4, U+1DE6, and U+1DEB should have insular variants.

Like æ, other ligatures involving a and e should be insularized: U+0153, U+1DD5, U+1DD6, U+A733, U+A735, U+A737, U+A739, U+A73B, U+A73D.

Consider an insular variant of ⟨j⟩ to match ⟨i⟩.

There are other glyph variants used in the medieval British Isles not included in FreeSerif. I am not sure if these are intentional omissions; this is why I’ve been asking about the scope of the project.
