Thanks for your support.
I think my software wasn't useful at the time of brainwallet. Now that the web service is closed, FSV seems more useful indeed.
Even if you have Electrum, FSV is much much more faster than Electrum. Also for verification, you don't need to fill every fields. Just paste in the text field the whole signature (PGP style with ----) and it will automatically extract the info. So you just need to paste and click on Verify.
If you use FSV and/or want to promote it, you can RT this Tweet :
