Given the asynchronicity of developer's life, I usually create a workspace for any microtask I have. And the workspace/microtask automatically dies whenever it no longer contains any window. Even looking for information on stack overflow is now a workspace in my workflow. (Because workspaces are so cheap).

After some weeks living like this, i see that some microtask survive for a surpisingly long time, and my workspace management has evolved into a kind of poor's man task manager.

The fantastic side-effect of a workspace tied to a task is that the windows, history, URLs are ready to use instantly. Which makes cognitive load when task switching a breeze.
