It would be nice if the ICON BLOCK on the landing page allowed for either an alternate link to be used or entering the text you want to display under the ICON instead of using the default which is to extract text from the landing page. As currently defined you have to make sure the text you have on your page works for both the ICON display and page display.
The icon blocks already support using the manual page excerpts (which are not available by default in WordPress but can be enabled with a plugin) on the landing page instead of the content.
The Plus edition is also capable of using custom links (using a companion plugin).
