Looks good. I can see only 2 main issues:
- What happens with a lot of wikis or if one wants to hide some wikis?
Put a field with autosuggest instead of the list?
autosuggest or revealing scroll
- Tricky mouse interaction -> we're talking
about small areas, might be
hard to aim correctly with the mouse -> maybe you could add ">>"
between
the
icon and the text to separate them a bit?
if you separate them too much they will look not look like a single item.
