If there was a way to give this 4.75 stars, I would. The free version is nice, but the premium version is amazing. It's clean, functional, professional, and easy to use for people like me that don't know how to code. It has quite a bit of flexibility built into it. It works well with a large array of plugins, too.
The good: This is a really simple, professional, clean look. I love the layouts with being able to separate my projects from my blog, from the features. It keeps things very, very organised and professional.
It also has a lot of flexibility for those that love plugins to touch up things here and there. I've put several on, and I've not run into a single functionality problem yet.
The neutral: For those of us that like lots of fancy extra short coding that we haven't learnt to do ourselves, like tabs and buttons, it lacks that sort of feature. Granted, this is a thing that some will look for and either celebrate or pout that it's not there.
The bad: I haven't come across anything bad yet. I really haven't. Normally I crash and kill themes or find at least 3 bugs by the end of the first week, but I haven't found a single thing yet in the two weeks I've had it.
