Remarkable collection; I use the Dvorak layout all the time. This is really a whole collection of many layouts  including Colemak  separate downloads. On the whole  it's designed well and works very well  but some more attention to detail would not be wasted. A quite-nasty bug  speedy runaway deleting backspace  has apparently been quietly fixed. I'd go bananas with delight if Menny arranged to license FITALY! There's a math. keyboard  but the numerals/figures shifts are no different from those for ordinary text entry. The repertoire of symbols is pitifully small.
