I love Publisher so far - it only crashed on the very first time I opened it, after 2 seconds (hitting command-F)
But the UI needs more love: In Separated Mode, when exporting documents, the toolbar hides the export-sheet -> which should be a free floating dialog box instead of a modal sheet. And it goes up in the popup-charts if you select MORE and then save presets... see screenshots.
Thats a mess!
