Computer system with a plurality of work environments where each work environment affords one or more workspaces

A computer system with an operating system that provides user access through a user account, each user account configurable by an associated user to provide a plurality of user work environments, each of the user work environments called a topic, and the plurality of user work environments comprising at least a first topic and a second topic, each topic providing one or more troves associated with user activity while the topic is selected as the user's current topic, the computer system providing a user interface that permits interaction with the second topic, generated by a user, that includes at least one associated workspace, the system comprising:

• data storage, operatively coupled to a processor, for storing trove data in one or more troves, each trove associated with an application executing while the user has selected the second topic as the current topic;
• the processor configured to execute instructions that cause the processor to:
• provide to the user of a first user account, the first topic, initially selected as a current topic corresponding to the first user account, wherein the first topic associates a first topic current workspace to the user as a user interface;
• respond to user selection of the second topic, different from the first topic, by,
• designating the second topic as the current topic provided to the user;
• associating a second topic current workspace with the second topic;
• and
• allocating a trove per application used by the user while the second topic is selected as the current topic;
• and
• respond to an external event to offer to the user an option to provide user input to switch to a different topic from the current topic in order to respond to the external event from the different topic.
