I like the "Preview" tab that opens up at the right-hand side as you're navigating among source code files. Great idea, thank you! It is useful for using 'Go To Definition' without causing clutter. As a further convenince
for navigating source code, please also forget the regions which have been expanded. It's always nice to open a code file and have all regions tidily collapsed. While navigating using the Preview tab, I do not wish being bothered to collapse
the regions after use.
