In the "Task options" there is the option "Set number of tasks shown as default" which is defaulted to 8. I have tried changing this to various numbers, logging in and out etc... but I just dont see any difference.
I Presume this option is for when viewing tasks, in the "tasks" view, to display 8 or more tasks. As a side note, it would be nice if there was an option "Show all tasks" or something along those lines, so we see every task that there is.
