Congratulations to Daniel and team for what has been built so far, and I hope the proper endings feature will be coming very soon. Until that time, I’ve come up with a quick workaround that I hope doesn’t look too bad.
I’ve created the endings as svg files in Inkscape which can be placed in graphics frames and resized as needed. Even notes ascending into the ending are accommodated fine. Ensure to set the Graphic “Fit mode” to “Fill” for easy placement. This approach, of course, has no impact on playback, just appearance. You would need to add these endings to the score and each part individually, which could get tedious if you have a lot of endings or parts.
