Displaying ontology browser

Ontology browser in the new version of ILIAS has been completely separated from Search and can be found via the tab 'Topics'. In my opinion, it might be better to integrate it on the search page. I know that it was not intuitive in the way it was in the previous version, but I think we need something in between.

Suggestions:
1. Add an extra search method:
Search method O Semantic
O Keyword
O Full text
O Definitions
O Ontology (opens as pop-up)

2. Extra option
Search method O Semantic
O Keyword
O Full text
O Definitions

Ontology browser O show O don't show
(opens as pop-up)

What do you think? I have the feeling that it will be now to 'hidden' for users, they don't expect it to be possible to search anywhere else than under the tab 'Search' (at least, that would be my expectation)
