First of all, I would like to say that I really enjoy using your application.
I have two suggestions for the program.
After scanning and saving a file as a PDF or an image, the application should automatically open the folder where the file was saved. It would be great if this could be added as an optional feature in the settings, allowing users to enable or disable it as they wish.
After I perform a scan, if I right-click to "view" the scanned item and, for example, perform a cropping action on it, I have a suggestion. If the resulting cropped item is smaller than A4 size, it would be wonderful if the application could place this new item at the top of a blank A4 canvas and then save the entire thing as an A4-sized PDF file.
I wish you success in your work.
