I have been using RW since version 3 and I have to say that Foundry is the most elegant, powerful, and EASY to use design theme/system I have seen to date.
I REALLY appreciate the over all design and the fact there are not SO many options it can become bewildering. Every time I explore a new stack, I am stunned and thrilled by, “wow, I did’t know it would do that!” Well done!
If you are on the fence, I suggest you give it a try. An extraordinary design tool.
