Its a good idea, and something the TODO list plugin was originally
intended to do, in addition to its current functionality. I am the one
who came up with the original idea for the plugin, but I am terrible
with Java so Gnonthgol coded it up based on my idea.
I wanted to also add the "area coverage feature" like you are describing
as well as a "follow along way" function so you could follow along
linear features like roads/waterways at some fairly close in zoom level
along a long feature and it would track which parts you have examined.
So I definitely think your idea has merit. My only quibble would be to
not add a second layer with squares, as OSM objects. You could do that,
but its a bit hacky. Also I don't remember how well the TODO list deals
with objects in other layers. Fortunately, you don't have to add the
squares as objects anyway, since the todo list can track them internally
without them being OSM objects, and plugins can draw to the map view
themselves. Think about things like the validator plugin (which draws
non osm object features to its own layer), or the fast draw plugin
(which draws non osm objects to the active map layer as temporary lines
that then get turned into proper OSM objects.
So aside from the implementation details, I would say yes, this is
definitely a good idea and one I would support being added directly to
the TODO plugin as additional functionality.

Dear fellow humanitarian mappers,
When I am mapping or validating a task from the tasking manager, I often
find myself "panning and scanning", that is, zooming into a level at
which I can quickly tell if everything that appears in imagery is
mapped, and then systematically panning over the entire area of the task
area (either with the mouse, or <ctrl>+an arrow key). This works until
I find something that needs to be mapped, or needs to be mapped
differently, in which case I zoom in, do the mapping... and forget where
I was with the "pan and scan" (keyboard shortcut "8" - zoom previous
helps a little, but if multiple zooms/pans of the map are performed it
can be difficult to "get back to where you were").
I have come up with a prototype of a new plugin which might help. It
divides the downloaded area in JOSM into a grid of smaller rectangles,
and adds the rectangles to the Todo List (also adds the rectangles to a
new data layer which is blocked from being uploaded from, or downloaded
into). As each of these rectangles is reviewed, you can "Mark" it in the
Todo List, and the Todo List will automatically zoom/pan the map to the
next rectangle.
Questions:
1) Would this be useful?
2) Does this functionality already exist?
3) Should I proceed with development?
4) Should it be its own plugin, or should it be combined with other
functionality of use to this community (for example, I could move the
duplicate building script functionality into this plugin)?
