Subject: Provide a hook for externally triggered search queries
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/27456a2f73b3d01cc94233fda958d0b22cb1ac5b

Provide a hook for externally triggered search queries

In this case the "From Here"/"Everywhere" buttons and the "Filename"/"Content" buttons are useless. Currently they just get disabled but the plan is to provide a better visual indication of the current query and to remove them completely.
