Hello Yoav!
I'm a computer science graduate student experienced with Android development (currently writing a master thesis about it actually). I think the changes that you propose are all easy for me to implement and I think I can do it quickly after we have talked about a few open questions regarding the design (colors of the menu, where to put the notes, show the menu always when viewed on a large tabled, ...).
If you are looking for a good solution and quick delivery, I am your guy.
Looking forward to hearing from you,
Best regards, Johannes
