Hiveminder's IM system supports the notion of context. Isn't it annoying to have to tell me what tasks you're talking about all the time?

Instead, with the context system, you can use this or these (makes no difference which one you use) in place of task IDs, like so:
create finish reading Dune [book dune] due this by thursday comment this wow what a great book! tag this [favorite] done this
The show command will list the tasks are in your current context.
