Ability to correct article sections, eg split, exclude, merge
When editing, I often find the selected "article" in fact includes multiple unconnected texts on the page. If I am going to help edit as I go anyway, I would rather I could fix this by eg, marking a line as being the end of an article, or not in the article at all when the selected texts are not related? Similarly, the ability to add by marking as part of the article when not currently selected. The thee common situations I see are: selected text continues past end of actual article (a split feature would help here); select text includes adjacent text from column to right (an exclude feature?); and selected text stops before actual end of article.
