As Laurent Savaete stated, The Markseen plug in does the job already.
When you put the parameters correct you have grip on what area you have
scanned and still to do.
fi. zooming till 20-30 meters gives enough detail to map, zooming out
for an overview does not effect the mini map with scanned area.
I always use it when validating large ( or collected small task) squares.
Best regards

Isn't the JOSM plugin MarkSeen
https://github.com/risicle/josm-markseen very similar to what you're
thinking about, or at least useful for your purposes?

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)?
Mike
