Option to scan all sheets while opening

[mad73923]

Hi there, thanks for your awesome piece of software! So far the best Excel compare / merge tool I've seen!

My feature request is the option to scan all sheets on opening ExcelMerge and show a summery of all diffs in all sheets. So far, ExcelMerge only informs you if there are no diffs on the first sheet (the message in the popup might be misinterpreted "there are no diffs"). Would be nice to extend the scope of this message on all sheets.

Thank you!
