Brackets on accidental; courtesy accidentals in general

First, I LOVE the improvements in note entry to 4.5, especially being able to add augmentation dots after note entry. Thank you very much.

I added a shortcut for adding a bracket to a courtesy accidental. This seems to default to square brackets. Is there a way to change this default to curved brackets?

Even with this improvement, I still have to enter the courtesy accidental with a keystroke, and then leave note input mode to select the accidental and apply the parentheses. I know there is a plugin to do this, but it would be nice if a single keystroke would enter the accidental, in curved brackets. (Like the P key in Finale!)

Should this post be in feature requests, instead?
