Just to add a detail, I would also like Markdown support when editing a page. Technically Confluence supports Markdown (or at least it used to) but after you saved the page it converted the content to it's own internal format and the Markdown was gone.

I would also like to be able to update a page through the API. Again, Confluence "technically" supports page editing through the API but it's so cumbersome that it's basically useless. The reason for this request is that we use our wiki to document certain activities (monthly security checks, AWS spend, etc.) and I have to manually update Confluence. It would be so much better if I could write a little Ruby (or Bash, etc.) to add content to a table in a page.
