This has been discussed for sometime, but doesn't appear to be high priority. I too would really like to be able to open up a separate task list window that I can leave open all day on one monitor, similar to how I keep certain notes open. Please give the user control of their windowing, don't assume.
I noticed some people talk about keeping all of the tasks in the default note. IMO, that defeats the primary benefit of tagging tasks inline in notes. Without that feature, there's really no point to using EN for tasks and not using a separate task app with better features.
