I tried to get the Restructure branch to try it out, but it appears that all
the download links (including Sourcecode) are broken. I'm getting a 404 on
every platform.

Subject: [Denemo-devel] A major re-structuring.
One of the most fundamental mistakes made when Denemo was first started was not
to have a structure for a Denemo measure. Instead it is just a list of the
objects in the measure. As a knock on effect, nothing can be stored with the
measure that applies to the whole measure.
This has made it difficult to fix the way that information about the context
(clef, timesignature ...) of an object is stored, especially when a measure has
no objects. It has long been my ambition to get rid of the way the calculation
of the context information is computed - a draw time. This is still causing
failures in Check Score on occasions.
As a start I have created a branch Restructure in which a staff now has a list
of Measure structures, which for now just has one element, viz.
the list of objects.
I've done a first trawl of all the code to try and make the change work
properly, and I've tested (with the default build) loading files, starting new
files, adding and deleting movements, staffs, measures, notes, chords, copy and
paste creating snippets, pasting and following them Undo and Redo.
It would not surprise me if I have missed something, it is perilous work. The
symptoms of an error are crashes, often with memory allocation warnings. But,
so far it seems good. If anyone can help testing this version that would be
good!
