MuseScore 2 bugs

MuseScore 2 bugs
version 2.1.0
Revision 871c8ce

1. Thank you for providing so many valuable shortcuts. They would be easier to remember if you included the chosen shortcut key displayed in the panel or workspaces top line (header) as a reminder. Then we can make/remove the panel easily when required, by simply pressing its specific key. For example, F11 > Play panel, but it does not include “F11” in the header display to remind us how to create/remove it. (I know View gives it again and I know esc removes it, but this would save time and key presses.)
2. Similarly undo (or redo) does not let me know what I am undoing, nor does the window shift to the item being undone.
3. Whilst MuseScore is running, but is NOT the active window, such as when I’m studying the MuseScore handbook .pdf, or typing lyrics in MSWord, MuseScore periodically forcefully becomes the active window, obliterating my chosen window. How do I prevent this?
4. “Add a hairpin” is easy. Inadvertently, somehow I had leftover hairpins in Piccolo parts’ rest measures but I could not delete them using click, (blue), del or backspace. How do I delete them? [I tried everything. Finally I tried deleting the Piccolo stave, and thereby lost everything, which undo would not resolve. After rebooting, “Load error…File corrupted. Expected ¾; found 36/24 (many times)”]
5. …Further… sometimes hairpins contract to a small > and sometimes hide behind other items.
6. Changing the dynamics in a part does not always result in a change in the score and vice versa. Add dynamics to a score sometimes results in stacked multiples of dynamics in parts and I do not know which is operating. Some are omitted entirely. This is a serious flaw.
7. Unwritten or not-displayed dynamics operated during play.
8. Insert bar/s at the beginning of a piece, and already inserted lines further on, do not move with their bars. (For example, all hairpins and dynamics in parts are corrupted and displaced.) Delete the bars just inserted, and any hairpins in those bars are deleted in parts too.
9. An option to synchronise scrolling in continuous view would save much hassle. For example, edit a part (say bar 116), change window to full score to see all instruments. I then have to remember 116 and find bar 116.
10. Similarly, with an item selected, increase zoom, and I have to search for the item again, as it has usually vanished from the screen.
