This has been released. Thanks for testing!

Today lwc brought to my attention that PDFTK Builder was updated several times without me noticing it. It is now version 3.5.1 with several improvements.
John, you said here that you have an ico file of the new Icon. It would be good if you could send it to me along with a new Splash so I can package the new version and do a Pre-Release.
And it would be cool John if you could do the redirect from https://portableapps.com/PDFTKBuilderPortable to the App´s page.
And while you´re at it you could redirect these too. Or maybe the new mods can do that...?
EDIT
Prerelase 1 of the new PDFTK builder has been released. It features a new icon and various improvements like the ability to drag-and-drop pdf files into the collate list, and several Bugfixes such as rotating pages didn't behave as expected and the sort order was ignored when more that 26 files were being collated into one file.

If there arent any problems with it, John can put in the new splash and release it.
