I love this program; I would also like to see a brutal mode for errors, or perhaps an option to set how much of your work you lose when you make an error (from 0 to 100%), set to 0 by default.

I look forward to this program developing.  My four dreams for it would be (1) easier to switch between keyboard layouts while training, keep the stats separate, without having to click around.  If it could tell which layout I'm in and split it accordingly that would be ideal, or even force me to switch between layouts.  I would use it to practice multiple layouts simultaneously.  Weird I know, but I would use it.  (2) Modes change in a pattern like Typing Master--variety would keep it interesting; (3) Being able to exclude certain keys, and progressively add in more (find sentences or practices that don't use the excluded letters, or create nonsense sentences out of them); (4) A fancy visible keyboard for the layout you're in, showing fingering via some color pattern.  This would again help use it to learn a new layout.

If a program handles it for me, that would be convenient, that's all.  If I'm practicing multiple layouts like I described, having to switch windows and open up and minimize and rearrange different keyboard images would be tedious.  There's nothing non-keyboard-agnostic about showing the user the keyboard they're using or helping them learn it; the program is awesome but to learn a new layout I currently have to use something else, that's all.  I believe its power could extend to other uses like I described.

As I already said, the problem is mainly that I would have to switch databases very slowly in amphetype.  Multi layout should not be that rare of a thing.  Many people should want to maintain their Qwerty speed as they learn a better layout.

Okay, I took a look at Amphetype. I does handle multiple databases nicely as far as I can see. What you'd have to do is simply to establish a database for each layout you want to learn and then start Amphetype with a command line switch! From the program's 'Database' tab: 'You can also specify a database name at the command line with the '--database=<file>' switch.' For Windows, that means adding the switch to the end of the path of a shortcut. So all you'd need to do would be to keep multiple shortcuts and you could even start up multiple instances of Amphetype at the same time I think.

For a help image and easy layout switching, PKL is still a Windows user's best bet as far as I'm aware of.

I'm talking about the full switch like what you're doing. Get a better computer...  ;)

It'd be possible to make a dual-layout, however. My way would be to use SGCaps - in my current MSKLC layout that's used to switch between greek and latin characters. I'm working on how to implement the ScrollLock key as another state key (the 'Kana' VKEY) so that I could put in Kyrillic, Hebraic and even another set. If you'd like to use that trick for multiple layouts however, you'd run into problems with the VKEYs. Can't redefine those on the fly, so one layout would typically have correct VKEY assignments and the other one not.

In your case, the Rulemak would (hopefully!) use the same VKEY assignments as the Colemak, and it's a go. SGCaps is your friend I'd say. Note that keeping the CapsLock key as it is in QWERTY may lead to unwanted switching. I use PKL's 'Extend' functionality to switch layouts with CapsLock+Esc instead.
