A great thing about open source is that people send emails now and then to suggest really good improvements to PdfMerge.
So this release incorporates two great suggestions from people who took the time to send an email with a good idea.
When in the grid area of the main form, you can now right click on any row. You then get a context menu item that allows you to select to either duplicate the current row to the end of the form, or to copy the file name to the bookmark.
You will also find a new menu item under tools that allows all file names to be copied to the bookmark. Can save a lot of typing!
Thanks for the great suggestions, and feel free to send more!
