Bug in tremolo rendering
Leaving aside the issue of different beam styles for a "between-note" tremolo, the beam positioning is unsatisfactory, in that it does not follow the normal beam positioning for regular notes. In the following test sample, bar 3 is a comparison with two ordinary (triple) beamed notes. Bar 1 is a tremolo, which should look similar, at the same horizontal spacing. (Not precisely, because I can't put them above each other) But in this tremolo the beams crash into the dots on the first note, because the beam is not adjusted as in bar 3. In order to make the tremolo look reasonable, I have to make it significantly wider, as in bar 2. It does not seem to be possible to adjust the beam position and stem lengths manually (and it wouldn't help much, because I've got pages of this stuff, and a tricky page break to engineer around).

I'm not sure it's a "bug" per se - there is no specific rule of music notation I am aware of says tremolo bars need to follow the same exact layout as beams. Our beaming rules are extremely complex and full of lots of special cases to try to produce optimum results as often as possible, with stem lengths in particular altered to create better beam layout (notice how much longer the stem of the second note of the pair in your third measure is comapred to the first note. Our tremolo rules are much simpler, basically consisting of, take the normal stem lengths and draw the tremolo lines accordingly.
That said, would be nice if it were possible to customize the tremolo angle, and might be especially nice if this happened automatically as you adjusted stem lengths. The fact that it doesn't, at least, could conceivably be called a bug. EDIT: actually, I take that back - the tremolo does adjust automatically if you adjust the stem length - it just doens't re-draw on screen unbtil the next layout (eg, after any other edit, or even just Ctrl+A). That much is a bug, albeit a very minor one. Anyhow, that's your solution for now - if you want control over tremolo angles, adjust the stem lengths.
