I wrote this review in Runestone

A good text editor is like a freshly sharpened chef’s knife. It just FEELS good to use, and it makes you happy. You know what a dull knife feels like and you can appreciate the perfect slicing motion you get from using the right tool for the job. Runestone is the right tool for text editing. It’s gorgeous, powerful enough to tackle editing huge files, and simple enough to jot down some quick notes or whip up a blog post for your static site. Combine this app with a git client, an SSH client, and you can manage your home software stack on the go. Finally, there’s not enough space here to say nice things about the developer, so I’ll leave it at - he’s incredibly thoughtful and responsive. If you have feedback on the app, hit him up on Twitter. Thanks Simon, for dedicating so much time to making this amazing app!!

Best Text Editor

I’ve tried so many text editors from Coda for iOS to Koder to Textastic. They’ve all been “ok”, but the problem I kept coming down to was the syntax highlighting. I’m a web developer and I use Atom on Mac every single day. I discovered this app and the syntax highlighting looked pretty good, but then I found where you can create your own theme and I immediately bought Premium and got to work replicating Atoms theme I use. I got it 90% of the way there and I’m in love. I’ve wanted this for years. THANK YOU.

If I could ask for anything it would be tabs for multiple files open at once and maybe a tree view on the left to browse files and folder structure, but other than that I LOVE IT.

The app is terrific so far, but _does_ have one problem

I’m editing files straight out of Working Copy, where I keep a local copy of my “dotfiles” project. Lots of files in there live inside directories that start with a dot, such as .config etc. Or the files themselves start with a dot, like .inputrc, .bashrc. I can’t figure out how to get to these files in Runestone. I wanted to report this as a bug but could not find the appropriate place to do so; so I’m doing it here. The app is great and clearly worth five stars so I’m not going to dock stars for this bug, but please, please, take this under consideration.
