Simple enhancements for Sharpen AI and other

Before I bombard you with new bugs requests, I would like to get several simple improvements.

Having worked a bit with MaskAI and Studio 2, I realized that I need using the mouse scroll zoom is necessary in Sharpen AI. Could you add this function since you have ready-made workable code for it?

I also ask you to add Open Recent, this simple function is also needed at least once a day.

Add mouse scrolling after clicking over parameter sliders for change parameters.

Buttons up and down or left to right, after clicking over parameter sliders for change parameters with a minimum step if the mouse does not fall into the desired number on the slider.

I have already created a request (Request #203764)
