XnView Software

When I use "Tools - Join Images", I do a lot of "try and error": change distance, change order, change other settings. The problem is - after every creation of a new "Strip" I have to select the files again. And again. ..

So it would be great if the software wold remember the last used files - for "always", because if I want to use new files I can used the already existing button "Remove files."
