Hello all,

I need a software application for Linux that allows me to store
unstructured information about e.g. my favourite restaurants, ideas &
thoughts about future projects, articles in scientific and political
newspapers, a whishlist for books and music etc. in a tree-like fashion. Tagging pieces of information for later searches would be a
nice gimmick. I need no mail-client or contact-management program. I
need no calender. If those standard PIM features are integrated - even
better.

Is there something like this?

Thanks a lot in advance
