:feature was a "catch-all" category. Many of its modules fit better in other categories, so they've been moved: - feature/debugger -> tools/debugger - feature/evil -> editor/evil - feature/eval -> tools/eval - feature/lookup -> tools/lookup - feature/snippets -> editor/snippets - feature/file-templates -> editor/file-templates - feature/workspaces -> ui/workspaces More potential changes in the future: - A new :term category for terminal emulation modules (eshell, term and vterm). - A new :os category for modules dedicated to os-specific functionality. The :tools macos module would fit here, but so would modules for nixos and arch. - A new :services category for web-service integration, like wakatime, twitter, elfeed, gist and pastebin services.
