Add an option to place the new table window next to the existing one in a row. I think you call this stacking.
In AGP Options, tables can be docked below the active map, stacked on top of the active view, as a separate floating window.
The "below the active map" option stacks vertically on top of an already open table. While that is below the active map, an option should exist to have it in the same pane area as other tables.
I tested each of the table placement options just now and noticed that regardless of the radio button selected, I can get the table to appear to the right of the presently displayed tables, for a time. After 30-45 seconds or so of inactivity, the behavior reverts to the option selected.
I would like an option to have the tables appear on the bottom of the screen (below the active map, but never stacked vertically), with newly opened tables appearing to the right of the already displayed tables.
