First thought: Most of the icons available have additional options built in if only they were exposed in the page builder.
Second thought: I hate repeatedly looking for the icon I’ve been using throughout the org. The “what was that icon for this?” thought.
Third thought: This can easily be slotted into the Design System with all the same types of controls as other component elements like buttons and fields. In this way we can customize things like this stuff for Font Awesome 4.
Then we can additionally give the icons descriptive names to easily find them.
Fourth thought: I would be awesome if icons could be set as a favorite and listed in their section when selecting icons.
Final thought: Font Awesome 5 Pro with styling and Icon Wizard!!! Oh my lord it’s so damn slick!!!
