Hi Decsites,
Super RSS Reader follows the same process like any other widget in WordPress. There is no intention to be cryptic here.
Widgets have UI to config the settings and shortcodes must be written since they can be inserted anywhere on your website (even in places where UI can’t come in)
Regarding shortcodes, I already mentioned it in my reply.
If shortcode, then you must build the shortcode using the example as mentioned in “Settings > super rss reader” page. It is quite simple and intuitive.
Regarding ” i STILL no way to change the appearance/view eg Grid”
Can you please share more details on what appearance you want to change? I can help with CSS if required. Also, can you please share your website URL where the reader is inserted.
Thanks,
Aakash
