Same here, that part of the flow seems like it could use some polish.

Two simple improvements could be:

1. make the "Search for icons" focused when the page loads (so the user sees a caret and that they can type something)

2. put a spinner while the logos load.

Yeah - gotta make that more clear. Even my smartest tech friends get confused there.

The moving suggestions and dotted-line empty spaces draw your attention away from the text field; maybe clicking on the suggestions/spaces should do something? Even just focusing the text field on click would make a big difference, I think.

Type a word or phrase then press ENTER. (Suggestions are scrolling below.)

THEN choose an icon from the suggestions. Clear your typed input, repeat.

I tried to click on the suggestions a few times, until I realized that I had to type ...

I had to hit enter and wait...and wait...and wait

Well, if it doesn't find any icons it will not change anything on the screen. :)

Should probably return a "We couldn't find anything like that :/" so you can know whether it's loading or just came up short.
