The Monitor window is the main window of Simon. At the top, it includes a toolbar. Along the left edge are mode buttons to enable switching the lists, logs or preview that is displayed in the window.
The top and bottom portions are separated by a splitter bar; you can drag the bar up or down to change the proportion shown. You can even drag it all the way to the top or bottom. Double-clicking on the bar will hide the bottom portion. Pro-tip: -click the selected mode button to hide that pane.
If no items are selected in the top list, the Info pane and logs or preview are for all items; if one or more items are selected, the information is for only those items. You can select multiple items by and -clicking the items.
