Does this feature cause more work than it saves?
This is a question you should always ask yourself. It is clear that the Confluence editor team has never seriously considered this.
The Confluence editor regularly creates 12 times as much work for me than a plain text document. Where possible I write documentation on Stack Overflow or create a gist on github and link to that. I have many unfinished documents that never get published because I can't get the formatting to not suck.
What can be done? Why does Atlassian not do something about this? There is no way that they use internally, what I am paying for, without hating it.
