Excellent work! I've attached a new file that addresses some of the issues you identify above: --) It uses axis-group::width to box accidentals --) It creates a FrameStub grob to occupy the horizontal space that a frame line takes up (note that I don't know if this actually works - I'm not sure how to test it - but at least it doesn't crash!). Whenever you have a spanner that somehow occupies horizontal space at its bounds, you can create stub grobs that approximate this space. This technique also works for items that, for whatever reason, have heights that are difficult to approximate (see SpanBarStub and StemStub, for example). --) It gets rid of some dead or unused code.
