Okay, that looks pretty good. It may mostly replace Jari Williamsson's Yada Yada Tremolo plugin, except do tremolos position correctly on whole notes in v26? If not, that may be the last holdout for the JW plugin.

Is there going to be built-in 2-note tremolo support (beamed and unbeamed)?

Okay, the new blog post answers my last question. Tremolos on whole notes position properly. Also, flipped staccatos on stemmed notes. Nice.

Another long-hoped-for development. Thanks.
