Toucan · Shipped Features

As of v0.22.0 (Windows, macOS and Linux). The WPF app is deprecated; v0.17.3 was its last release. Release notes are in CHANGELOG.md; open work is in todos/future-roadmap.md and open bugs in known-bugs.md. This file lists shipped features only: when something ships, add it here and delete it from the roadmap. Unless a line says otherwise, a feature is in the Avalonia app, the app on every platform. Lines marked (WPF) shipped only in the WPF app (last release v0.17.3) and are not in the Avalonia app. The Avalonia app does not have the Source Control and Dictionary panels yet; its Translation panel is the Machine Translation panel.
