show the list of all layers and allow someone to select one, put in a filter and
run it and it adds the features and zooms to their extent. It may also allow the data to
be downloaded and displayed in the app or as a CSV etc. Could allow sharing the query to a
uset or app.
here we can take the context layer that is selected on the left
(or other) and we can allow it to be filtered for display as well
as allow download of the data as a CSV and so on.
The icon should light up if we can interact. Also the "secondary" tab
can maybe become an icon or soe other way of saving horizontal space.
