Eclipse Juno - In my workspace I have \'Package Explorer\' opened on the left side, on the right side I have 6 visible file tabs and under \'Show List\' I have 17 files.
Quick Linux fix for all themes:
cd
find . -type f -name "*.css" | xargs grep 'swt-mru-visible: false' | cut -d: -f1 | xargs -n1 sed -i.orig 's/swt-mru-visible: false/swt-mru-visible: true/'
This will find all CSS files with "swt-mru-visible: false", back them up with *.orig suffix and change to "swt-mru-visible: true"
You can find all backup files with"
find . -type f -name "*.orig"
