This looks great although the pricing is a little too steep. Also it'd be great if I had the ability to add custom elements to the page.
When I use a tool for work, I want them to charge enough to stay in business so they can 1) continue to exist (and I don't have to look for a replacement), and 2) continue to make improvements.
I can think of a hundred tools that were cheap, but died or got stagnant or let bugs fester because they couldn't afford to hire devs.
