- the on-blur action for the language input was modifying the language property in the payload object directly which meant that the mobiledoc `save` call was missing and all the associated editor behaviour for serializing and saving the update was lost
- switched to modern action syntax and a proper action on the backing component so we're saving the change correctly
no issue
- show the toolbar icon for any `<KoenigCard>` instance that has the `saveAsSnippet` action passed to it
- currently that's all cards except the HR card because that's a primitive element rather than containing any user-defined content
- add `koenigUi.inputHasFocus` so that card toolbars can be hidden when the snippet input is displayed
no issue
Keeps component JS backing files and template files in the same directory which avoids hunting across directories when working with components. Also lets you see all components when looking at one directory, whereas previously template-only or js-only components may not have been obvious without looking at both directories.
- ran [codemod](https://github.com/ember-codemods/ember-component-template-colocation-migrator/) for app-level components
- manually moved in-repo-addon component templates in `lib/koenig-editor`
- removed all explicit `layout` imports as JS/template associations are now made at build-time removing the need for them
- updated `.embercli` to default to new flat component structure
