LOGICAL, SAFE, AND MORE PERSONAL USER INTERFACE FOR ACCESSING DATA AND LAUNCHING PROGRAMS OR APPLICATIONS

Logical, safe, personalizable, and user friendly computer user interfaces may include: (a) plural branches; (b) plural sub-branches associated with the branches; and (c) an interface control that includes: a branch locking interface, a sub-branch locking interface, a branch display control interface, and/or a sub-branch display control interface. Optionally or alternatively, user interfaces may include: (a) a first section including plural items having a first common visual characteristic; and (b) a second section including plural items having a second common visual characteristic. In this manner, the common visual characteristics may indicate an association between the items sharing the characteristic. This associative visual characteristic aspect may be applied to the branched user interface structure described above, for example, by commonly coloring at least some portions of a branch and its associated sub-branches while commonly coloring at least some portions of another branch and its associated sub-branches in a different color.
