[multi-scan] Make UI for scanning from ADF more easy to use
Created by: Jonny007-MKD
Typically I scan ~10 documents with varying number of pages via ADF. The UI could be improved so that I can enter the number of pages more simply: the field for the page count could already selected when the window is opened. When I press Enter in this field (or perhaps Shift+Enter or something) a new entry is added and the field for the number of pages is already selected so that I can continue adding documents without using the mouse. For example, I could then open the ADF window and start typing: 3 {Enter} 2 {Enter} 4 {Enter} 1 {Enter} and have defined 4 documents.
