For the latin alphabet,
- UsingCapitalLettersToMarkNewWordsInASentenceInsteadOfSpaces.
- Reintroducing Þ, Ð, Æ, and Œ to facilitate more phonetically consistent spelling.
- Nixing the goal of one sound one letter in favor of allowing digraphs where the IPA also uses digraphic construction, IE using Tc to represent the ch sound given that T makes a ta sound and C makes a sha sound.
- More use of ' for where words have been shortened in pronunciation, Being -> Bein' for example.
- letters for sounds that may not be in your language but are still common enough to be worth being able to transcribe, X for thr kh in Khubz for example.
For a entirely new script,
- Consonants are single stroke glyphs with no closed loops or shapes
- Vowels are single stroke glyphs that must have at least one loop or shape
- Hangul style consonant blocks with Chinese character style stroke order for how to place the individual glyphs
- mark a full word by drawing a box around it.
- write sentences top to bottom, and then from left to right
