2.1 please make real buttons out of the the - and +, very hard to hit without border around them

The chrord edit mode in 2.1 is so great, but it’s getting more obvious for me that just using a character as a button, I mean the - and +, is really hard to hit with the mouse.

I know that the hit area is bigger around, but a border around like a typical button would make it so much better to use.

You need to see the real hit area to be easy to hit at with the mouse pointer. I can quite easily compare it to buttons in other plugins. I can hit smaller buttons very easy with the mouse, when the hit area is visible, like a typical button.
