DelightEd & Podofyllin

DelightEd – Rich Text (RTF) editor with special Dark Mode features and support for interlinear text

DelightEd works as a full-featured Rich Text (RTF) editor in Sierra and later, with similar features to TextEdit but without support for graphics or RTFD. In Mojave, though, it can switch to full Dark Mode, and gives control over the whole app’s behaviour and individual windows. Supports regular colours for text and background, URL links, and in Mojave supports textColor markup for text which switches mode properly. Ideal for viewing RTF saved from Consolation 3 and Nalaprop. Has live word and character count. Notarized for Mojave. Opens and saves plain text, HTML and PDF files, as well as RTF. Version 2 adds support for creating and working with interlinear text, such as multiple translations of a document.
