When I'm in a forum and I click 'Search forums' at the top, 99% of the time I want to only search the forum I'm currently in. Instead I have to find it again from the large list of forums in the small box. Could the current forum be selected by default? Or another 'Search this forum' link added at the top?
I guess this has also been addressed somewhere else or nobody cares, but I do, too. @AngryAnt I saw you commenting on the thread related to Forum searching, recommending inquisitor (ok, that was 11 years ago, amazing). Can you, or do you know who can do this? Searching a particular forum easily would be nice.
A 'search this forum' is definitely needed. Its absence feels inconsistent given how similar the forum UI is to the thread UI.
