[IDEA] show counts of matches in the sidebar search inside the dropdown

[ittayd]

The search in the sidebar allows plugins to add other searches than the default. However, the number of results of the default search is shown outside of the results dropdown (next to the arrow) which is confusing.

Would be nice to show the results inside the 'List' tab, or, show the number of results next to the drop arrow but according to the selected search tab.
