When editing in Wikipedia, I also often have more than 6 tabs open and often visually lose the tab on which the answer was started in the Reply tool or the edit started in the Visual editor, because out of habit I am looking for the tab with "Editing" in the title. I have to manually drag the tab to the beginning so that it becomes the first and I can easily find it. Some kind of marker in the header for a page in an editing state would be helpful.
Sometimes I have to open two versions of a page to view different parts of a long discussion. Sometimes I don't send messages instantly and they stay in the editing state for tens of minutes, at this time other pages open and many pages accumulate with a similar beginning of the namespace in the tabs. And if I scroll to other comments, for example to the beginning of a long thread, so that the edited place is outside the visible area in the browser, then when I return to this tab it looks like a usual inactive page - it takes time.
