Custom Time Signature
I have compiled 2.0 from source today and had these problems. I could not test them on the nightly builds because they are not running, at least here in my computer, giving some strange error, but I think probably it would be the same as the code compiled here. (Btw I never know if I should post stuff like this in Technology Preview or Support and Bug Reports)
I tried to open the Master Pallete and create a new time signature. I created a 5/4 measure that shows as 3+2/4. When I click add, it appears in Master Pallete alright. First problem is that if I drag this new time signature to my score it appears as 5/4, even if it appears as 3+2/4 in the Master Pallete window. The second problem is that I can't add it to the normal Pallete. I does not allow me to drag this signature to the Pallete or nothing like that. The same thing is happening to Key Signatures. They all appear as a empty signature when I drag my custom Key Signature to the score.
Also, in 1.3 I once used a tupled based signature (like 8/6) and it almost worked. The playback was right, but in the notation program just approximated the duration in 64th notes. I was really expecting to be able to do this correctly in a future version, but it looks like the possibility to put a denominator that is not a power of 2 was just removed instead. Pretty sad.
