For those working with Rich Text without embedded images, my free editor DelightEd offers a suite of unique features. I wrote it when macOS Mojave introduced Dark appearance mode, with the primary purpose of composing Rich Text documents that work independent of appearance. For that it can set styled text on a background that ensures perfect readability in both Light and Dark modes.

Since then it has gained other unique features, including support for creating interlinear text, in which different translations or versions of the same document are interleaved line by line. It will also open PDF documents and automatically extract all their text content.

General features supported include Writing Tools (Apple silicon Macs), case transformations, and a full suite of substitutions. However, until this new version of DelightEd, substitution settings haven’t been saved in DelightEd’s app settings. Version 2.5 now puts that right: to set the app’s default substitutions, set them up using the Substitution command in its Edit menu, for instance enabling Smart Links.

Then save those to its settings using the Save Defaults command in the app’s menu. Each time you open DelightEd after that, its substitutions will start from those saved defaults.

DelightEd version 2.5 for macOS 11.5 Big Sur and later, including Tahoe, is now available from here: delighted25
from Downloads above, from its Product Page, and through its auto-update mechanism.

I’m very grateful to Manuel for asking for this to be fixed.
