sbsettings is the best. I recommend you go do a search in cydia for sbsettings and look thru the results. You will find their are are few add-ons called widgets for sbsettings for example Fast Notes. I've added all I could find. They are all great quick shortcuts.
Allows you to jot a note down with SBSettings and then open SBSettings to view it in any app. For example, say you had a bunch of numbers (a confirmation code or something) and you had Safari open and you can't memorize the entire code, you could jot it down on Fast Notes, open Safari, then open SBSettings > select Fast Notes and view it that way.
With all of the copy/paste solutions now available, however, Fast Notes becomes pretty obsolete, unless you encounter something that you can't actually copy with Clippy/hClipboard.
