Another problem with the Aptana 3 themes: The color of Occurences (Pydev) in
General -> Editors -> Text-Editors -> Annotations does not go well with the
Pydev dark theme (white on yellow). Shouldn't these settings be part of the
theme? Is there a way to switch of the Aptana themes completely? it has been
so much better without the theming stuff.

You can edit the occurrences color as usual (under window > preferences > general
> editors > text editors > annotations > occurrences (pydev).
Note that in the current nightly build you can disable the theming support (in
the pydev editor preferences).
