I would like some tools to help find unbalanced tags.
They might include:
1. lines to connect begin -end tag.
2. indented listing
3. hit some key to jump to the matching tag.
4. collapse inner guts of a tag pair so you can see the forest for the trees.
5. smart tag inserter. It figures out the 3 most plausible places to insert a missing tag or tag to remove, and lets you select, perhaps seeing the rendering for the various possibilities to help you choose.
