Retain previous open file tab under visible tabs

Question

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.

Answer 1

I think I just had the same problem and I solved it by switching the theme.

Go to Preferences -> General -> Appearance and switch to the Classic theme.

I can't understand why this helps, but it worked for me.

Update:

After being bitten by this again I checked again and as @anweibel says in his answer this can be edited in the CSS.

I just installed the E4 CSS editor plugin using the Eclipse Marketplace so that I could change the CSS directly from Eclipse under Preferences -> Apperance. I changed swt-mru-visible from false to true so that the relevant part for the GTK theme looked like this:

.MPartStack {
    font-size: 11;
    swt-simple: false;
    swt-mru-visible: true;
}

A restart was required for the changes to take effect.
