That is already possible, unless I am misunderstanding.So don't change the local thing but see to that one can combine one local keyboard setting with keeping English everywhere else in menu and program texts.

I have tested by booting the live cd and formatting the hard disk to ext4, then installing a full install and rebooting. it worked fine. Then I reformatted to ext4 again and made a frugal install, that worked fine also, but you do have to manually edit the /boot/grub/menu,lst as the instructions say. this was on my old P3 Thinkpad T22.
WhoDo has also made a subtle change that makes the active titlebar easier to read. He agreed with those who made comments--but it read fine on some computers. I have implemented that change. As we speak 01micko is putting the finishing touches on Quickpet. Don't expect anything today, but get ready for tomorrow! It's coming....
