Re: totem opens favorite folders instead of Nautilus
When you want to open a folder with totem or some other application, the intuitive way is right-click folder and choose "open with..."
Then if you keep the "remember this program..." option totem will become the default program to open that folder and users get confused because suddenly default behaviour changed.
So what's counter-intuitive here is that the "remember" box is checked by default - and maybe that the description is a bit misleading. It could read something like "change default program for this folder" instead.
On Ubuntu since December 2005 (5.10 onwards)
