问题
I have been using Indigo for a while, and now trying Juno
There is a sligth bothering difference:
On Indigo When you had 10 tabs opened
A | B | C | D | J | H | G ....(F | T | S)
and currently on B
when you selected the file shown in tab T again, then this tab (on Indigo and that's the problem not on Juno) would be repositioned like that:
A | B | T | C | D | J | H ....( G | F | S)
This is useful since, if opening T after B, it means they should be grouped together
on Juno it does not reposition them, instead you will need to find most recent files far in the tab list
Q: how to set it back? I searched params with 'tabs' in the options with no result
edit: still the same in new versions (Kepler)
edit: Thanks to Paul' answer, a good solution is to search for .css files in eclipse folder, and set swt-mru-visible property to true in e4-default-win7.css for example
回答1:
Juno by default doesn't present the MRU (Most Recently Used) tab behaviour that you see in Indigo (it never worked quite right) and instead uses the Editor document order.
I believe you can re-activate it be either switching to the Classic theme in Preferences>General>Appearance or by editing the CSS. See http://wiki.eclipse.org/Eclipse4/CSS
.MPartStack {
swt-mru-visible: true;
}
Don't forget to restart Eclipse to make it use the new parameters.

Apparently this option was added in Eclipse Mars 4.5:
Window -> Preferences -> General -> Appearance ->
Visible tabs on overflow:
[X] Show most recently used tabs
