Anyway, to come back to the point, Secret Ballot is a way to make the whole game rely on luck and eloquence instead of logics. Depends on what you prefer, but it heavily favors the mafia - not the neutral roles though, because it is really easy to get someone lynched. I prefer the standard trials, where the votes are public. It makes it really harder for an Executioner or a Jester to win, and forces mafia to have a real, solid alibi and to be able to work independently. When using a secret ballot, on a day without any clue, if people don't skip for any reason (conversation for example), you can decide to eliminate a player with a quick, combined vote. And no one will ever know who did it. And you can do it again the next day. And as you say, a Disguiser can even take an important role without being spotted.
And the Blackmailer, as it is, isn't a real Blackmailer, he only is "muting someone", without denying him communications. With the Cooldown, no spam, and the chat becomes that much easier to read. As for the duration...5s isn't that much for a 1.5 min day. With 10s, you can easily vote if it is needed, but you won't rainbow, unless you are very patient, and people are really observant.
