Before: what you give it

The example input, as typed in. You paste text, CSS, markup or notes.

Make it pop more
I don't like the blue
The checkout button is the same grey as the cancel link, so people will not know which one finishes the order
Can we use a carousel here?
Feels off

After: what comes back

The first lines of a real run on that input. Nothing here is edited by hand.

5 notes: 1 observations, 0 solutions without a problem, 1 opinions, 2 vague, 1 questions. 20% ready to act on.

[vague] Make it pop more
   "Make it pop" cannot be acted on; say what you see that gives that impression
   Observation: on the [element or screen], I see [what is actually there].
   Impact: because of that, [who] will [do or miss what].
   Suggestion: [optional; a direction to try, not an instruction].
[opinion] I don't like the blue
   a preference with no effect attached; say who it affects and how, or drop it
   Observation: on the [element or screen], I see [what is actually there].
   Impact: because of that, [who] will [do or miss what].
   Suggestion: [optional; a direction to try, not an instruction].
[observation, ready] The checkout button is the same grey as the cancel link, so people will not know which one finishes the order
[question] Can we use a carousel here?
