When you delete a document in AppFlowy you see a dialog appear at the top of your document:
No such dialog appears when you delete a Grid, Board or Calendar. Since there is no indicator of the file being deleted, the user may continue editing the Grid/Board/Calendar without noticing that they have deleted it.
This is how it appears:
How to Reproduce
Open AppFlowy
Create a new Grid/Board/Calendar
Delete the newly created item from the sidebar
Observe how the deleted item still appears without any indicator of it being deleted.
Observe how you can still change the deleted item’s content.
Expected Behavior
Some indication that the Grid/Board/Calendar is deleted and thus should not be modified.
