This is the tool I've been looking for.

It allows me to create graphics to help explain key ideas and concepts easily. I don't want to build something from scratch.

I played around with the free account for a couple of weeks. And finally pulled the pin and paid for this deal. It's been great to see new templates being added to the site over the last couple of weeks.

Only 2 things I can think of that would improve the experience for me.

1. More fine tune control over colours. I'd like to pick a part of the graphic and be able to change the shade of the colour. Sounds like brand colours is coming soon from previous replies to comments.
2. Alignment of text. Currently if I write new text on each line within a part of the graphic it's centered. Sometimes I'd like it to be left aligned.

But apart from that, a really solid solution for creating graphics for my website and social media. I like you have the ability to get a SVG version of it. If you're on the fence, play around with the free version.

One other thing that I noticed which seemed strange, on the website there doesn't seem to be any way to contact them. They should probably look into that.
