Hi,
I absolutely agree with James and Joseph on this issue. As James wrote this 'scroll of death' is possibly the most significant usability problem with Moodle.
Oleg, my feeling for why this has not been implemented is not the same as yours. I feel that historically Moodle developers have lacked understanding of user experience and usability. The question for me is not whether developers think this feature is necessary, it is more a question of would this feature significantly improve the user experience within Moodle? I believe it would do. Of course the only way to establish whether this is true or not would be to carry out a usability test. NB this is not the same as suggesting if users wanted this they would request it through the Moodle forums.
Mary, thanks for the workaround tip. I believe also that other people use the book module to avoid the total cognitive overload of showing all course content in one go. I realise there is a mechanism for showing/hiding topics but it is not well designed and is itself a signficant usability problem.
From everything I have read about user experience my understanding is that if you have any significant amount of content it should be chunked and there should be sub-navigation by clicking on text or graphical labels/links. In effect this is what the book module does. It gives you a menu of links so that you can see the structure *without scrolling and experiencing cognitive overload*.
I will be trying out the above options in the next week and will feedback on what method I feel works best for users.
