It’s easy enough to count syllables, but it’d be expedient if the number of syllables were automatically counted for a given line, and that number were automatically shown/updated either passively or on demand.
I have seen other plug-ins make use of the margins, such as Lapel which shows H1 in the margin next to an H1 header.
Not sure if my request is possible but I’m sure poets and song writers would appreciate and I’d certainly pay for monthly coffee/ko-fi for something like this!
