1. Delete multiple footnotes
2. Rich Text Editor: add Paste As HTML option.
3. UI improvement
4. Bug fix
Here are some UI changes when editing chapter:
Text and image shortcut icons are added to the top navigation bar to make it easier to complete common tasks: add paragraph and images. Tool icon is used to add other elements.
Chapter heading is moved above element list. It can show more characters for long heading.
Publish button is moved next to preview icon. It becomes consistent with fixed layout editor. The flow is much more clear now: after previewing, the next task is publishing.
Paste As HTML option:
By default, content which is pasted to rich text editor becomes plain text in order to avoid invalid characters. From 3.8, tap action icon and then select "Paste As HTML" action. It can keep style of content.
