I submitted two fedwiki pull requests today.
When I was digging into how copying/moving paragraphs between pages worked, I discovered shift-click-drag to copy.
However, I found that after doing a copy, if I edited or deleted the original, the copy changed as well. It was just in the UI, if I refreshed the page everything fixed itself.
Interestingly enough, after following a link from the fedwiki chat I found the following on Ward's wiki.
Copying a paragraph is made hard too since you have to remember to hold the shift key down while dragging and ignore the fact that it seems to have moved the item anyway (It hasn't, refresh to see that.)
I'll have to chat with folks to see if they want me to implement this. Since I'm refreshed on the subject I can do it easily.
That is pretty self-explanitory. If a page links to another page via reference, it should show up in the backlinks.
