Very often, like daily, I use the preview window to look at an epub with an intention to change some headings to something else. This request is for the cursor to show up in the code window at the same point as clicked in the preview pane. Sometimes, it does that, but other times it goes to the start of the line. If you then try to change the heading to, say, <h2 (CTRL-2) a whole section of the ebook is enclosed in the <h2, and the ONLY way out is to undo. And wait. And wait.
Ideally, if I click a character in the preview, the cursor would go to that character. But it would be ok to be anywhere in that line EXCEPT before that line, because in order to change that heading, you not only click in the preview to get to the line, you THEN have to click in the code window inside that line in order to change its heading. If you forget that second step - undo. And wait. And wait.
