Have a 'Select All' option when selecting the mapping properties
I have SmartObjects with more than 150 fields. For adding all those fields as input mappings I have to check each and every field. Beside that I just can check 7 fields at once in the small pop-up, then I have to scroll a little down by dragging the very tiny scroll bar and then I can check the next 7 input fields and so on!
It would be much better to just click on a select all button to add them all.
