Dear Leslye,
I apologize for the manual mention, it is something that had to be removed since we left only one icon pack in the plugin (removed all that were third-party and added the one made by me specifically to match the overall look and feel of Ikebana). There are no specialized widgets envisaged in Ikebana to insert the same icons as in the header, for the sake of better user experience (distinct styling of header and footer). However, you can use a plain text widget and insert the icons into it to match the header icons – they are created using Font Awesome, which is quite easy to use.
Sincerely,
Andrew / Satori Studio
