I agree Confluence is a pain to use, and pages with a lot of info or a lot of macros can been nearly impossible to edit because of how slow they are.
On your point about inserting code blocks you should be able to type `/code` and hit enter. If you’re not using the newer version or a page with the new editor, I think you type `{` instead of `/` but it’s been a while since I’ve used that one.
to mark off a code block, and to use Java syntax highlighting (for example).
That's when you are editing in "raw" mode, which, incidentally, I haven't been able to discover how to do in the New Issue View (which I finally discovered how to turn off, that is to say, switch back to Old Issue View, globally -- it's under account settings, yay! The "New Issue View" is a lab setting you can turn OFF.)
You can also change an issue from the new view to the old view by selecting "switch to old view" from the More menu (three dots).
I have to say, it's painful using Atlassian tools after having worked with GitLab for 5 years... I miss being able to use standard markdown in Issues, and editing the Wiki using Git/vi instead of in a text box in a Web browser, with strange markup.
