Anchor panel suggestions

[MikeTO]

Some minor suggestions to improve the Anchors panel:

1. The Anchors panel could use a Show/Hide Anchors option just like the Index panel has for Index Marks. There's space to add the little toggle icon that Index has.
    
2. Use double-click as a shortcut for go to anchor. Currently double-click does nothing.
    
3. Add Collapse Nested Anchors and Expand Nested Anchors commands to the panel menu.
    
4. Add a Show Hierarchical toggle command to the panel menu similar to the Text Styles panel. It currently only shows anchors as hierarchical but sometimes it would be nice to view them in an alphabetical list without the parent-child relationships. When viewing it alphabetically, you wouldn't be able to drag an anchor onto another one to create a relationship.
    
5. Users shouldn't mess with anchors generated by the TOC. There's no point making an anchor generated by the TOC a child of another anchor because it will just move back out when you refresh the TOC. If you rename an anchor generated by the TOC then you'll wind up with a duplicate anchor (and all of its child anchors) when you refresh the TOC. Perhaps TOC anchors should be locked or provide a warning if you try to mess with them?

Thanks,
