What's New

Version 4.0

• Added full support for Dark Mode on macOS Mojave and improved the user interface.
• New syntax highlighter: Textastic 4 has a completely new syntax highlighter that can use Sublime Text 3 syntax definitions (in addition to language grammars from TextMate 1). This means much better support for modern features in almost all supported programming and markup languages.
• Added syntax definitions for TypeScript, Rust, and reStructuredText. Updated syntax definitions for almost all other supported languages.

Does not break your Default App Extension settings (Updated)

As others have noted, Textastic appears to override your macOS default app settings for some files, i.e., GetInfo and Always Open With options don’t seem to work. On macOS this occurs when the file is stored in the Textastic iCloud folder and is a macOS/iCloud instituted behavior, not something done by Textastic. Since this is not a Textastic issue and the app is otherwise excellent - no reason not to give this app five stars. Thank you to the developer Alexander for his support in very quickly identifying the concern.
