The number one change I wanted to focus on was making sure that the Donate button was the first thing the site visitor saw when they landed on the page.
In the original design, the Donate button was buried under text. I wanted to make sure that the call to action was front and center. Also, because the "Cover Fees" option is important, I keep that at the top but gray it, make it smaller and put it just below the Donation button so it's present but not too much in the way.
Future considerations are whether or not we can embed the Tithe.ly form rather than have the site visitor click it to summon a modal.
