Provided herein are systems, methods, and software for implementing information management applications. In an implementation, at least a portion of an information management application is embodied in program instructions that include various task modules and a scheduler module. In some implementations the program instructions are written in accordance with a single threaded programming language, such as JavaScript or any other suitable single threaded language. When executed, each task module returns control to the scheduler module upon completing. The scheduler module identifies to which of the plurality of task modules to grant control based at least in part on a relevance of each task module to a user interaction.
