Media user interface gallery control

One or more computer-readable storage media comprising computer executable instructions that, when executed, direct a computer to output a user interface having a gallery region and a pivot region:

• the gallery region comprising:
• a plurality of representations of media items that are horizontally arranged to form one or more horizontal carousels and vertically aligned to form a plurality of columns;
• and
• a center-locking region encompassing a portion of the plurality of representations such that at least two or more of the plurality of columns of representations of media items are positioned within the center-locking region and at least one of the plurality of columns is positioned outside the center-locking region, wherein the center-locking region is fixed to a pre-determined area of the gallery region that is less than a total area of the user interface, wherein a user is not able to move a focus of the user interface horizontally outside of the center-locking region, wherein the center-locking region is configured such that:
• each representation is capable of receiving focus and being selected when positioned within the center-locking region;
• and
• each representation is disabled from being focused or selected in the user interface when positioned outside the center-locking region;
• and
• navigating the plurality of representations of media items in the gallery region of the user interface comprises:
• scrolling, along a horizontal direction, to cause one of the plurality of representations outside the center-locking region to be positioned within the center-locking region when horizontal navigation is attempted from one of the two or more of the plurality of representations located within the center-locking region to one of the plurality of representations located outside the center-locking region, wherein the focus is shifted to the representation scrolled into the center-locking region;
• and
• the pivot region is positioned vertically adjacent to the gallery region and including a plurality of representations of features that are:
• configured to sort the plurality of representations of media items in the gallery region;
• and
• arranged in at least one horizontal carousel accessible via vertical navigation from the gallery region.

One or more computer-readable storage media comprising computer executable instructions that, when executed, direct a computer to output a user interface comprising:

• a list comprising a plurality of representations of media items, the plurality of representations being horizontally arranged from left to right to form one or more horizontal axes in the user interface and vertically aligned to form a plurality of columns, the plurality of representations comprising at least a first representation and a second representation wherein the list is displayed as a horizontally-oriented carousel;
• a gap vertically positioned in the user interface and indicating a beginning and an end of the list by separating a beginning column and an end column of the list;
• and
• a center-locking region encompassing a portion of the list, the center-locking region having a height sufficient to include all of the one or more horizontal axes in the user interface and having a width sufficient to include three or more columns of the plurality of columns of the list, the center-locking region being configured such that:
• each representation is capable of receiving focus and being selected when positioned within the center-locking region;
• and
• each representation is disabled from being focused or selected in the user interface when positioned outside the center-locking region,
• wherein:
• each representation located in the center-locking region is navigated when a focus is shifted to the representation from another representation;
• and
• when navigation through the plurality of representations of media items in the center-locking region causes the gap indicating the beginning column and the end column of the list to be positioned within the center-locking region, the gap separating a plurality of columns in the center-locking region into a first portion of columns including the beginning column of the list and a second portion of columns including the end column of the list, navigation further comprises moving the gap out of the center-locking region by:
• navigating horizontally from the first representation to the second representation to cause the gap and the first portion of columns to be positioned outside the center-locking region on a first side of the center-locking region and to cause two or more columns that are positioned outside the center-locking region to be positioned within the center-locking region on a second side of the center-locking region when:
• the first representation is located in the second portion of the columns within the center-locking region and the second representation is positioned outside the center-locking region and on the second side of the center-locking region;
• and
• the first representation and the second representation are horizontally aligned and positioned next to each other;
• or
• navigating horizontally from the first representation to the second representation to cause the gap and the second portion of columns that are located within the center-locking region to be positioned outside the center-locking region on the second side of the center-locking region and to cause two or more columns that are positioned outside the center-locking region to be positioned within the center-locking region on the first side of the center-locking region when:
• the first representation is located in the second portion of the columns within the center-locking region and the second representation is positioned in the first portion of the columns within the center-locking region;
• and
• the first representation and the second representation are horizontally aligned but separated by the gap, such that, after the navigating:
• the first representation and the gap are positioned outside the center-locking region and the second representation is still positioned within the center-locking region;
• and
• the first representation and the second representation maintain separation by the gap.
