grid view settings improvement needed

[bachig26]

Is your feature request related to a problem? Please describe.

the slider for the grid view adjustment is kind of difficult and can't be changed or re-adjust easily.

Describe the solution you'd like

i would like to see these two kind of options for this to be more easy or to achieve output faster.

1. add an value input box.
2. add a mouse scroll over the slider option to adjust the values.

Describe alternatives you've considered

1. value input box is like an text box or similar to how the 'Opening duration' and 'Small skip' input box in the media player menu.

2. mouse scroll over the slider is like an option to adjust the slider similar to the app like eartrumpet where it's used for adjusting the volume slider.
