try! Swift 2019 Native macOS application, or the world of AppKit © 2019 1024jp CotEditor Seriously, I tried hundreds of different text editors, I'm extremely picky and I couldn't believe I found this one. Tons of features and customization options, but also straight to the point and really fast. Excellent code formatting, excellent native, minimal UI. No useless extra features or weird themes. It launches instantly on any machine. I use CotEditor every single day for every text related task, and it's all I need. #1 text editor for Mac Nov 10, 2018 | Italy ˒˒˒˒˒ I was looking for another really light-weight multipurpose editor with proper syntax highlighting that was Cocoa native. This will finally replace Smultron which I loved until the developer thought he was a designer and fubar'd the UI. Particularly love being able to customise line height, because this is too often forgotten, Kudos for this app. Finally, another lightweight and simple editor Jul 14, 2017 | Japan ˒˒˒˒˒ This is the one what I'm looking for whole this time. I was looking for simple text editor with mac os interface elements and some basic features. I gave up searching. I decided to develop one on my own. And, I almost start to develop. Then, I found this app. It's saves my time. My request: Only I missing is project file directory as sidebar. This is the One Dec 1, 2018 | Sri Lanka ˒˒˒˒˒ Great code editor! /* Please add a left Sidebar */ Simple, Powerful, and True to macOS UI Feb 1, 2019 | United States ˒˒˒˒˒ 4.7 out of 5 346 37 11 4 8 ˒˒˒˒˒ ˒˒˒˒ ˒˒˒ ˒˒ ˒
