Designed by programmers who are "modern" GUI designers. Orange colors, graphics are a bit oversize and clown-like, but it does everything it claims to do very well. As an old-school programmer, once you get past the graphics it is a more useful tool than the competitors. I like the ability to create a GUI to edit metafields. Works well for me, but tough to train end-users. All and all a good app that does what it claims.
The best metafield editor I've tested. Only downside - it's really slow and glitchy on files of 1000 lines or more, so I have to break down my imports into multiple go's. Other than that - it's super handy.
