+You first need to initialize targetView, before using any of the view manipulation functions.

+#### targetView
+```typescript
+targetView: ExcalidrawView
+```
+The open Excalidraw View configured as the target of the view operations. User `setView` to initialize.
+
+#### setView()
+```typescript
+setView(view:ExcalidrawView|"first"|"active"):ExcalidrawView
+```
+Setting the ExcalidrawView that will be the target of the View operations. Valid `view` input values are:
+- an object instance of ExcalidrawView
+- "first": meaning if there are multiple Excalidraw Views open, pick the first that is returned by `app.workspace.getLeavesOfType("Excalidraw")`
+- "active": meaning the currently active view
+
+#### getExcalidrawAPI()
+```typescript
+getExcalidrawAPI():any
+```
+Returns the native Excalidraw API (ref.current) for the active drawing specified in `targetView`.
+See Excalidraw documentation here: https://www.npmjs.com/package/@excalidraw/excalidraw#ref
+
+#### getViewElements()
+```typescript
+getViewElements():ExcalidrawElement[] 
+```
+
+Returns all the elements from the view.
+
+#### deleteViewElements()
+```typescript
+deleteViewElements(elToDelete: ExcalidrawElement[]):boolean 
+```
+
+Deletes those elements from the view that match the elements provided as the input parameter.
+
+Example to delete the selected elements from the view:
+```typescript
+ea = ExcalidrawAutomate;
+ea.setView("active");
+el = ea.getViewSelectedElements();
+ea.deleteViewElements();
+```
+
+#### getViewSelectedElement()
+```typescript
+getViewSelectedElement():ExcalidrawElement
+```
+
+You first need to set the view calling `setView()`.
+
+If an element is selected in the targetView the function returns the selected element. If multiple elements are selected, either by SHIFT+Clicking to select multiple elements, or by selecting a group, the first of the elements will be selected. If you want to specify which element to select from a group, double click the desired element in the group.
+
+This function is helpful if you want to add a new element in relation to an existing element in your drawing.
+
+#### getViewSelectedElements()
+```typescript
+getViewSelectedElements():ExcalidrawElement[]
+```
+
+You first need to set the view calling `setView()`.
+
+Gets the array of selected elements in the scene. Returns [] if no elements are selected.
+
+Note: you can call `getExcalidrawAPI().getSceneElements()` to retreive all the elements in the scene.
+
+#### viewToggleFullScreen()
+```typescript
+viewToggleFullScreen(forceViewMode?:boolean):void;
+```
+
+Toggles targetView between fullscreen mode and normal mode. By setting forceViewMode to `true` will change Excalidraw mode to View mode. Default is `false`.
+
+The function will do nothing on Obsidian Mobile.
+
+#### connectObjectWithViewSelectedElement()
+```typescript 
+connectObjectWithViewSelectedElement(objectA:string,connectionA: ConnectionPoint, connectionB: ConnectionPoint, formatting?:{numberOfPoints?: number,startArrowHead?:string,endArrowHead?:string, padding?: number}):boolean
+```
+Same as `connectObjects()`, but ObjectB is the currently selected element in the target ExcalidrawView. The function helps with placing an arrow between a newly created object and the selected element in the target ExcalidrawView.
+
+#### addElementsToView()
+```typescript
+async addElementsToView(repositionToCursor:boolean=false, save:boolean=false):Promise<boolean>
+```
+Adds elements created with ExcalidrawAutomate to the target ExcalidrawView.
+`repositionToCursor` dafault is false
+- true: the elements will be moved such that the center point of the elements will be aligned with the current position of the pointer on ExcalidrawView. You can point and place elements to a desired location in your drawing using this switch.
+- false: elements will be positioned as defined by the x&y coordinates of each element.
+
+`save` default is false
+- true: the drawing will be saved after the elements were added.
+- false: the drawing will be saved at the next autosave cycle. Use false when adding multiple elements one after the other. Else, best to use true, to minimize risk of data loss.
+
+### onDropHook
+```typescript
+onDropHook (data: {
+  ea: ExcalidrawAutomate, 
+  event: React.DragEvent<HTMLDivElement>,

+Callback function triggered when an draggable item is dropped on Excalidraw.
+The function should return a boolean value. True if the drop was handled by the hook and futher native processing should be stopped, and false if Excalidraw should continue with the processing of the drop.
+type of drop can be one of:
+- "file" if a file from Obsidian file explorer is dropped onto Excalidraw. In this case payload.files will contain the list of files dropped.
+- "text" if a link (e.g. url, or wiki link) or other text is dropped. In this case payload.text will contain the received string
+- "unknown" if Excalidraw plugin does not recognize the type of dropped object. In this case you can use React.DragEvent to analysed the dropped object.
+
+Use Templater startup templates or similar to set the Hook function. 
+
+```typescript
+ea = ExcalidrawAutomate;
+ea.onDropHook = (data) => {
+  console.log(data); 
+  return false;
+}
+```
