When we are using any action then it has feature to zoom in and zoom out using (ctrl+mause scroll wheel ) and UI is look like this for 0% and 100% respectively

I want this feature In main screen as well because in reactive if you add heavy content(more content) then at certain point Y scroll is not work that time using help of widget tree developer developed app
if this feature will implement then will see our screen and it will be better instead of now.(its my point of view )
