It would be useful to have a possibility to configure the Quick search feature to search in entry titles only. For me, that's where I'm searching almost exclusively. When I would need any more complicated search (that happens maybe once a year), I would use the full Find feature.
Why I need the Quick search to search in entry titles only: I have many website accounts connected with Google or Twitter, so I'm authenticating through them. In entries for such websites, I have a note that it's connected with Google or Twitter. Now, it's impossible to find the Google or Twitter entry using the Quick search, because it finds hundreds of entries.
In Options > Interface > Quick Search (toolbar), add a checkbox Search in entry titles only.
Go to the full search (Ctrl F).
Select Title and nothing else.
Save as a custom search (Title only?)
Now use Ctrl F to search.
The setting you used will be remembered between sessions.
