Abstract: Systems and methods for recommending and implementing network documents for users to offer items in a marketplace may be provided. A system can obtain user data that includes an item offered by a user in a first electronic marketplace. For example, the system can identify and catalog items offered by a particular user. The system can identify a second electronic marketplace for the user to offer the item. The system can determine implementation information for the second electronic marketplace. The system can generate a network document for the at least one item that is configured to be presented in the second electronic marketplace based at least in part on the implementation information.

Abstract: Techniques for generation of user interfaces include accessing data indicative of a plurality of values and including a subset of the values in a user interface. The subset may be selected based on user input or the characteristics of the device for which the user interface is generated. Each user interface is associated with a device characteristic, such as the size or shape of a display area or the presence of an audio output device, and the characteristics of the user interface may be determined based in part on the device characteristics. When a request from a user device is received, correspondence between the device characteristics of the user device and the device characteristics associated with the user interfaces is used to determine which interface to provide to the user device. Changes to values in a first user interface are included in other user interfaces accessed using other devices.

Abstract: Disclosed are various embodiments for displaying content. A display area includes multiple information regions presenting content. Visual characteristics associated with the information regions adjust according to values corresponding to the to the information regions. For example, the sizes or positions of the information regions may adjust according to the values.

Abstract: Disclosed are various embodiments for handling large collections of items in a user interface. A collection of items in a data store associated with a request for a content page is identified. A content page is generated that includes a number of items in the content page, where the number of items in the content page can be less than a total number of items in the collection. The content page also includes a select-all element. The content page is also configured to initiate a subsequent request to with an argument corresponding to activation of the select-all element as well as potentially an exclusion list corresponding to deselected items.

Abstract: Disclosed are various embodiments for displaying content associated with a merchant selling items through an electronic commerce system. A display area includes multiple information regions presenting content associated with the merchant. Visual characteristics associated with the information regions adjust according to values corresponding to the to the information regions. For example, the sizes or positions of the information regions may adjust according to the values.

Abstract: Technologies are described herein for presenting resale opportunities to purchasers of resalable items. An identifier of a resalable item is received. A number of resale estimates are determined for the item and presented to the purchaser of the item, and the purchaser indicates whether or not he or she intends to resale the item at a future date. Upon receiving an indication that the purchaser intends to resale the item, a resale prospect is stored containing the identifier of the item, an identifier of the purchaser, the date for resale of the item, the resale estimates, and the like. The purchaser may then be presented with at least one reminder regarding the resale of the item on or near the date for resale. The reminder may further include the resale estimates and a facility allowing the purchaser to quickly and easily initiate resale of the item.
