I've not yet gotten used to the extra twist features, but I think they will
prove a very powerful tool. I like the way you handled showing/hiding
pieces of certain colours. If there's one thing I could suggest, however,
it would be to always show the 1C pieces regardless of whether they are
checked or not. These can be very important in keeping the cube properly
oriented.

These improvements definitely warrant the progression to v0.1. I think I'm
ready to make a legitimate attempt at solving it. Great work!

Wow, that's quite a significant set of meaningful changes! One of the
reasons why I was asking about animation last time was because seeing
animation of a sequence of moves makes it easier to undo the sequence when
conjugating a macro. But with your F-key features that makes the step of
remembering the exact sequence of moves you used to put the puzzle into
position to apply a macro much easier. It also makes building macros on
commutators a much easier step as well. Nice job! Still too many pieces i=
n
7 dimensions for me to want to solve it, but I definitely want to play with
it ^^

Yes, conjugate. I forgot the existence of this term, shame on me... I know =
about twist counting bug (start/stop macros are counted as twists) and I'm =
not sure that I'll fix it soon. May be, I'll do "cleanup" command that remo=
ves all macro marks and pairs of rotations of the same face in opposite dir=
ections, and so restores the twist count, but not in the next version.
Thank you and good luck! v 0.11 is coming soon ))

Sorry for frequent updates, but couple of bugs in v0.1 was very serious. So=
new version is in the same place: http://shade.msu.ru/~astr/MC7D/MC7D.zip=
.
New feature: command "Recalculate" (in Edit menu). It performs all twists =
again, from the solved cube, without all Undo/Redo branches. I recommend to=
run it from time to time to be sure that your puzzle is in state consisten=
t with the twist history (and that it's solvable :) )
