At the request of several users, I have added the ability to define your own labels for the Search Window tabs. You can also control whether or not the tabs will wrap if they won't fit on one line. Right click on a tab and look at the last two items. Use should be self explanatory. It's limited to Roman characters.
Until this is tested a bit, it is only available as a beta version. To see the download you have to open up the updater in BW and click on the options menu. Enter "BW8BETA" as the access code (no quotes). Then the update should become visible. Take a look if you are curious, but only if you are comfortable with a test version. The risk is small for this one though.
