The current features of "Ecwid: Random products" module are below.

==
* You can add shortcode to display random products in the body of your page. 
For that you should use the following shortcode:
[ecwid_random_products number="5"]

where number="5" defines how many products should be displayed. 
You can omit this parameter and in this case 3 products will be displayed.

If you add "show_title" parameter to shortcode, then the product's name will 
be shown under product's thumbnail

If you add "show_price" parameter to shortcode, then the product's price will 
be shown under product's thumbnail

You can use shortcode for displaying random products horizontally. For that
you should define parameter "as_row" and add parameter "per_row" as how many
products should be displayed in row. E.g. shortcode
[ecwid_random_products number="10" as_row="true" per_row="5"]

will display 10 products in two rows per 5 products each. You may want to
define one product's section width when using row-mode. In this case add
"product_width" parameter, which will define single product's section width in
pixels.

==
* You can add random products to sidebar using widget. For that go to the 
Widgets section in your Wordpress admin area and drag 
"Ecwid's random products" widget to the appropriate sidebar of 
your theme. Then define its options to adjust the widget's appearance.
