Search FIRST for titles
When searching, it should display on top cards with matching TITLE first, and then all the rest.
Example: when you search for "Yahoo", "Gmail" etc. with intent to find the cards on your e-mail accounts and instead it shows you ALL the entries with fields containing "@yahoo.com" or "@gmail.com" in them - which are too many to provide you an effective search.
I think I might have come up with an idea that would please this your suggestion too.
Check it out, maybe vote it, it's titled: «Sort by MOST USED (both when searching and when just opened the app)»
