[Feature Request]: UI Possible improvements - "Fit to Page" & "Fit to Width" & "Full-Screen" Explicit Buttons.

Feature Description

Could PDF Viewing options for Stirling PDF Possibly include options such as adding user friendly buttons such as fit to page on both height and width similar to how Google and Edge built in PDF Viewers have it? It could improve user friendliness on windows devices.

2nd topic; Touching on this, could removing the "Make Stirling PDF your default..." banner after every boot up be made an option? such as a checkbox in settings or something such as "Always ask if 'default PDF'" be unfilled thus not displaying banner. But this isn't main topic and has already been mentioned in Issue #5772.

Why is this feature valuable?

Would like to have a single PDF App that can be used for everything intuitively, without feeling the need to use Chrome or other apps to view PDF's

Suggested Implementation

If possible, add these buttons.

Additional Information

Options currently not present at least for me.
