Best Text Editor Around

This app is such a bargain. You get a really good editor for free, or, even better, the perfect editor for just a few bucks. If there were a Mac version, it would be my default editor alongside vim. This app offers syntax highlighting for every file format I could ever need, even including LaTeX. And the interface, including the file browser, is clean and simple. I wish I had found this app earlier.

I love this app

I have fallen in love with this app. It is my go-to text app for writing.

I do have one feature on my wish list: word count.

Can you please add a word count option on the status line? That would take this app over the top for writers.

Please?

Simple and clean

I like the simplicity of the app. Would it be possible to add a preview view for html or markdown? Let know if it’s in premium purchase and I’ll get it asap.
