- update `{{koenig-card}}` component to compare payload values and create a snapshot when exiting edit mode for container cards (markdown, html, code)
- update image card to trigger snapshots on image upload/selection and width change
refs https://github.com/TryGhost/Ghost/issues/9724
- focus was not being returned to the editor after the Unsplash modal was closed so although the image card looked selected the editor was not responding to any key commands
refs https://github.com/TryGhost/Ghost/issues/9724
- standardised `{{gh-unsplash}}` actions and action arguments to better represent a generic "image source"
- added `{{gh-unsplash searchTerm="ghosts"}}` parameter
- added `payload` param to `card` definitions used for plus/slash menus so that default payload params can be passed to cards
- added a concept of "image selectors" to image card
- if a `payload.imageSelector` param is received by the card it will look it up in it's list of known selectors and display the appropriate image selection component
- if the card was created with an image selector param and the image selector is closed without selecting an image then the card will be removed
- delete image cards during cleanup if they were created via selector but have no src

- added `{{koenig-basic-html-input}}` component
- uses a stripped down version of Koenig
- supports all inline formatting that Koenig supports
- supports inline text expansions
- supports inline key commands
- limited to a single paragraph
- serialises and deserialises from HTML rather than mobiledoc
- updated `{{koenig-caption-input}}` to use `{{koenig-basic-html-input}}`
- updated image and embed cards to calculate word counts correctly for html captions
- bumped Spirit dependency to fix styling of toolbars within the editor canvas
- fixed positioning in toolbar components to account for `parentElement` not necessarily being the closest element to position against
refs https://github.com/TryGhost/Ghost/issues/9724
- add `registerComponent` hook to cards so that `{{koenig-editor}}` can fetch properties from card components directly
- add word count and reading time utilities
- add throttled word count update routine to `{{koenig-editor}}` that walks all sections and counts text words or fetches word/image counts from card components
- add `wordCountDidChange` hook to `{{koenig-editor}}` so that word count + reading time can be exposed
- modify editor controller to update it's own word count property when koenig triggers it's action
- modified the editor template to show reading time + word count next to the post status
refs https://github.com/TryGhost/Ghost/issues/9623
- do not process drop in `{{koenig-editor}}` if the drop happened on a card and the card's `handlesDragDrop` property is true
- allow `dragover` events on cards to bubble up to Ember's event handler in `{{koenig-editor}}`
- handle drag/drop in `{{koenig-card-image}}`
- show different overlays when dragging files over the card to indicate an upload or replace action
- start upload when a file is dropped on the card
refs https://github.com/TryGhost/Ghost/issues/9623
- add new `{{koenig-caption-input}}` component
- yield koenig-caption-input instance from the `{{koenig-card}}` component
- remove duplicated caption logic from image and embed cards
- remove placeholder when caption input has focus
refs https://github.com/TryGhost/Ghost/issues/9623
- update `{{koenig-card}}` to show the toolbar immediately if it has changed
- update `{{koenig-card-image}}` to only add toolbar items when an image is present
refs https://github.com/TryGhost/Ghost/issues/9623
- detect pastes that contain image files and insert a card for each, setting `payload.files` to the `File` instance grabbed from the clipboard
- update the `addComponent` hook to ensure the `payload.files` array is preserved, browsers do not allow `File` instances to be copied
- update `{{koenig-card-image}}` to look for a `payload.files` value to auto-upload it via it's internal `{{gh-uploader}}`
- NOTE: browser support for accessing image files on paste varies:
- Safari: will paste all images
- Chrome: will only paste the first image
- Firefox: will not paste any images
refs https://github.com/TryGhost/Ghost/issues/9505
- use Spirit classes for card context menu
- add button and icon class options for context menu items
- add ability to have icon+text for context menu items
- add "Edit" context menu item to markdown and html cards
refs https://github.com/TryGhost/Ghost/issues/9311
- add actions for cursor movement and pass through to card components
- `moveCursorToNextSection` deselects card and places cursor at beginning of next section, useful for caption inputs where <kbd>down arrow</kbd> or <kbd>right arrow</kbd> should move the cursor out of the input & card. Also creates an empty paragraph before moving the cursor if for some reason an empty paragraph doesn't exist after the last card in the doc
- `moveCursorToPrevSection` deselects card and places cursor at end of previous section, useful for caption inputs where <kbd>up arrow</kbd> or <kbd>left arrow</kbd> should move the cursor out of the input & card
- `addParagraphAfterCard` deselects card, creates a new paragraph after the card and moves the cursor to it. Useful for caption inputs where <kbd>enter</kbd> should have the same behaviour as if it was pressed whilst the card is selected
- modify `{{gh-uploader}}` so that it passes the FileList to it's `onStart` closure action. Useful for displaying previews when uploading images
- modify `{{koenig-card}}` toolbar display so that it can display text as well as icon buttons
- update `{{koenig-card-image}}` so that it has a full image uploader and caption input
refs https://github.com/TryGhost/Ghost/issues/9311
- adds the `koenig-card-image` card that renders an `<img>` element
- adds text expansion to convert markdown images into the new image card
