It's probably been 'improved' by someone who's paid to make 'improvements' and who would be out of a job if he/she failed to make them.
Much the same happened with the Radio Times website. At one time it was possible to store settings with one's favourite channels at the top of the list and with others further down. Then the site was 'improved' and that facility disappeared. More importantly though, to find out when a particular programme was coming up, all one had to do was to search for it by name. Now though such a search is likely to bring up loads of articles about the programme but absolutely no indication as to when one can actually watch it!
It's called "progress" :)
