Several Questions regarding playback

I will try to be civil about this, as I already hate coming here for help.

So, there are several things I have questions about with this update, such as:

1. Why are grace notes not played correctly? In the example, ms 13 and 14 in the third stave, the grace note is played WAY too early, and I can't get it to play on (lets say) beat 31/32, aka a 32nd note before the next measure

2. Why is it when I copy and paste tempos now, I can only do so in the first stave because any other stave somehow copies every previous tempo and pastes a double of it on whatever stave I pasted it to? It's annoying.

3. Why do I now have to take ages using the arrow keys to move tempos to the side? When I move a tempo marking, it also moves where it is played. Previously, I could have a tempo halfway across the page, and it still applied to the first beat, let's say. Now, if I go across the page, it moves the tempo to be changed on like beat 4 of the literal next measure. Again, annoying.

4. Why do I have to constantly pull up a custom workspace because it won't save and keep my workspace as a default and instead goes back to the original default?

5. (general question) When will the roll editor be added, if it ever will? That was a good feature that could at least help me with the grace note situation.

6. (general question) When is the piano player going to show the light up notes while it is playing (like in MS3)
