Is there a character profile tool that makes it easier to play as many characters just wrye bash and wrye mash does for the other two TES games?

Another question, is there a way to increase the amount of save slots?

I don't know what those programs are in the slightest. They seem to be about conflicting mods. Daggerfall doesn't have mods like Morrowind/Oblivion do; if you mod DF, you alter the game files directly. And there aren't that many mods for DF anyhow.

As for more save slots, you can always just copy the save folder into another directory. You won't have easy access to more than six saves at once, but if you want to store a character for safekeeping, that's the best way to do it. Keep the six accessible slots for current characters.
