I've been trying to customize the toolbars in Eclipse (Kepler, JavaEE) for quite some time now. After finally getting the toolbar configured the way I want in a given perspective (say, the main JavaEE perspective), when I switch to a different perspective (say, the Debug perspective) and then switch back, it's completely messed up. Additionally, if at that point, I re-open the dialog to re-configure the toolbar again, I find that it's no longer in sync with the current state of the toolbar.
I've also tried saving my configurations as a custom perspective, with no effect (still does the same thing).
Overall, it seems that this aspect of the Eclipse IDE is almost completely broken. I'm currently on a completely updated version, but this has been the case for a while, and I've seen it happen in many previous versions.
I would LOVE to be wrong about this. Is there a way to be able to properly configure the toolbars in Eclipse? (and have it stay that way)
This question was the first hit in my quest to find out how to customize the toolbar in Eclipse at all... so expecting others don't know the answer either it is:
(menu) Window > Customize Perspective
from there one can manage toolbar and menu items.
This is a known issue here. It looks like it should be fixed in the next release.
