If I may, here's an old wish that I will resurrect:

In the Editable Notation Mode, make the Rest checkbox sticky and make it work on Notes and Rests both.

Full disclosure: Peter and I did discuss this perhaps two decades ago, and he considered it but chose to keep it the way it is.

Explanation:

To delete a note now, you have to take two steps: right-click, select Delete. How about a checkbox so you can click on a note to delete it? That would make editing a song quicker; just scroll through the song linearly and click to delete any note you wish.

However, even this two-step method does not work with rests. You cannot right-click on a rest. To erase a rest, I think you have to go through a bunch of steps:
Melody menu
Edit Melody
Step-Edit Melody
scroll to the Event that has the rest
click Delete
click Close

Let's have the checkbox for rests work for inserting or deleting a rest, and make the checkbox a sticky.

Bonus points for anyone who knows the un-intuitive key to hold down to delete more than one rest in a row, and can find this answer in less than two minutes. Yes, there is an answer.
