Not bad.
A lot of people are probably looking for more language support, but in its first iteration this app is great. It came in handy in a pinch. The reason I didnt give it 5 stars is because it does not offer any options for changing the text size or zoom level of the document youre working on. It also doesnt offer any advanced features such as line shifts as found in TextWrangler. Again, pretty good for its first version, but I hope to see updates that add more features in the future for my money. :D
