Design Implications:

• A system shouldn't try to be too helpful to the point where it is closing things for the user or deleting objects that seem useless, because the suer might be keeping them around for a reason.
• Allow for hands-off flexibility within a system. For example, give people the tools to create their own reminder systems, and retain data for an unfinished task, which also supports the deferred choices pattern and agrees with the heuristic of "user control and freedom."
• You can implement many workspaces which lets users leave unfinished pages open while they work on something else.
• You could also provide a readily accessible list of "object of interest" for things gone unfinished in the past as well as things with potential to be used in the future.
• Additionally, you can think about gathering reminders from different sources into one place
