The export window no longer holds settings in memory for future exports
I often need to export multiple videos from one project. Each sequence used to hold its settings for future exports. Now I have to change them for every export. For example the bitrate of an H264 file. Or, I have to turn timecode on every time...etc. Having a separate window for filename and destination is also counterintuitive, as I can't click a previous export to change the filename, which was a huge time saver.
