This came up in https://invent.kde.org/documentation/develop-kde-org/-/merge_requests/368. And we discussed this years ago in Phabricator, in https://phabricator.kde.org/T12777, but we're not consistent about the icons we use for deletion and removal, and there are some conflicts and inconsistencies stemming from it. Status quo: - Closing windows/dialogs/tabs: either a black X (in the window decoration) or a red-circled X (via the `window-close` icon) - Moving things to the trash: a black trashcan via the `trash-empty` icon - Deleting things from disk: a red trashcan via the `edit-delete` icon - Removing list items or other abstract UI elements like Plasma widgets from the view/current configuration: sometimes a red trashcan via the `edit-delete` icon, and sometimes a red X via the `edit-delete-remove` icon - Icons with "remove this thing" badges in the corner *usually* use a red X for the badge, but sometimes a red minus sign (e.g. `kt-remove-filters`) and sometimes a red trash can (e.g. `mail-deleted`) The status quo causes various issues: - Using a black trashcan for a common non-destructive action ("move to trash") and a red version of the same action for destructive actions isn't ideal - Using a red X for various close icons isn't ideal since red means destructive, and closing dialogs and windows isn't destructive - The red trashcan icon for destructive actions can't be used universally since it doesn't easily fit in the corner as a badge, so we end up mixing our visual metaphors Proposal tor fixing it: - Commit to using a red X for _all_ destructive remove/delete action icons, as well as the remove/delete badges in the corner of icons - Use a black X for the window/dialog/tab closing icon, to be consistent with the black X using in the window decoration. - Stop using the red trashcan icon entirely. It's too similar to the black one Thus, our remove/delete/close icons will be simpler, clearer, and more consistent. It also largely mirrors the rough conclusion in https://phabricator.kde.org/T12777, which was that we should use a red X for irreversible deletion and a black trashcan for reversible deletion. @teams/vdg @teams/usability @depmann
