I use IntelliJ IDEA for editing my HTML pages. Usually I split the editor window and switch one of the windows to Mozilla preview. During editing I can see immediately preview of the changes.
It works fine until location of the changes exceeds the preview window. I can scroll the window to the desired location but any consequent change in the source window causes setting the preview window to the initial position.
It would be perfect if the preview window was kept the scrolled position so the possibility of immediate preview will be available for any editing location.
It also would be nice to have adjustable repainting period of the preview window and repaint the window in background.
