There are still skeletons but a lot of the page components load instantly(cached) and others load quite quickly.
Tons of UI "jank" has been cleaned up across Jira and Confluence. The UI design, in general, has also finally cleaned up nicely and "settled".
Confluence articles load very fast now. They have also added Live documents which is a very welcome addition.
Is Jira still bloated? Yeah, but that doesn't preclude improvements. It feels less bloated now to me.
YMMV.
I don’t know exactly what the other issue is referring to.
Looking this up now, Wikipedia says the wiki markup was abandoned already in 2011. Not that I think Confluence was ever a great wiki, but at least having pages that were backed by some resonable plaintext markup was much better than not having that.
Everything else has been UI changes as far as I've seen.
If anyone from atlassian reads this: please, for the love of god resolve this issue.
