I'm really a big fan of this new feature, I put it on ctrl+s because it saves so much time to select groups of files. Most often used to select .rar, r01, r02... sad thing is, many multi disk archives are part01.rar, part02.rar and so on. And it doesnt work there.
Enhancement: the first time you execute this command on a file, all without extension are selected, the second time, the last two "extensions" are ignored and selected, and so on. With this it should be much easier for me

to select part01.rar archives. Just ctrl+s and ctrl+s.
I hope you understand my idea, and I hope even more you like it.
