If a setting could logically be in many places it's a pain to have to search through them all until you find the place someone decided was 'the one true place.' This is especially true for rarely used things as you're less likely to remember where it was next time you're looking for it. Nokia have been making it even worse recently because 'the one true place' varies from model to model. I expect this is one of those UI decisions without a right answer. 'Intuitive' depends on people's expectations, and we don't all expect the same things. _______________________________________________ Shr-User mailing list [email protected] http://lists.shr-project.org/mailman/listinfo/shr-user
