Mind, if it's on the 'recent topics' I'll post. I'm not digging through 4+ pages of apps to find it unless I'm all there and happy. And not posting from my n900.

On desktop Linux, yes. On the N900... I doubt it's so easy. Remember, the whole system's kludged together.
I, too, have my desktop Linux system, and I, too have copied the home directory between installs... It usually works, but will often leave behind cruft; differences between application versions can have different config file formats, let alone the simply leftover bits that don't end up getting used. On a desktop system, who cares? On the N900, where every MB counts in the optfs... it's an issue.

And yes. That's the great thing about linux. Don't want to implement someone's (silly?) suggestion? Tell em to do it themselves!
In this case, though, it's not hard - Just pull out a text-editor and get to work!
