Search mode's blue outline around matching tabs is too thin, difficult to find

[roeyk]

How about making the blue outline 2-3x thicker, or just shading all the items that match the query?

I also find that the blue outline is too easy to miss. I'd suggest to gray out (or desaturate) all the items that DO NOT match the query, and also to add a match counter next to the search entry field.
