Feature Request: Option to group task by page name, tags, or namespace

[cleanclothes-pi]

Thank you for a very useful plug-in.

Currently, all tasks outside of journal pages are grouped together as "ANYTIME". While I find this useful in normal cases to let me know what I got to do now, sometimes I want to be able to see and manage tasks in different project (pages) at a glance.

That said, it would be great if we can have a button for "group by ...", with the options: page names, tags, namespace. For fluidity, I suggest that these options appear below the pop up rather than having to go into plug-in setting.

All the best!
