    I've been sort of busy lately and haven't gotten around to doing many changes
    to femm lately. Anyhow, what I want to do is make some sort of "release"
    version of femm before really adding any more functionality, so that there
    can be a relatively bug-free "standard" version. Basically, I things seem to
    be pretty stable (except for a couple sort of odd-ball bugs that cropped up
    lately), and I really just need to update the documentation to reflect all of
    the difference and additional functionality between the 2.1 and 3.0 versions.

    Then, there can be a new "official" development version that will include
    some of these suggestions, as well as Robin's lua extensions and some other
    stuff from Hang (bitblt stuff) that I haven't incorporated yet. The stuff
    that has been suggested that would be reasonable to tack in are:

    1) Marker at the origin.

    2) Highlight areas that the solver doesn't like because no material
    properties have been identified

    3) Some sort of "Preferences" so that one can control the default view setup,
    colors, etc.

    4) Copy a bitmapped image of the view, as well as metafile image.

    There is some technical functionality that I'd like to add in, like:

    1) Nonlinear harmonic problems based on a describing function approach

    2) Figure out how to do time transient solutions in combination with the
    scripting

    3) Maybe some sort of airgap elements to aid in problems with rotational
    motion.

    In response to some of the other issues:

    Grid "alignment" move around because, depending on the zoom, only a subset of
    the grid points are shown. If all of the grid points were displayed, the
    screen would tend to fill up with blue at when zoomed out. However, the
    physical alignment of the grid (i.e. what location the grid points map to) is
    constant, regardless of the zoom setting.

    I don't know about the multiple undo levels. This probably wouldn't be that
    hard to implement, and it probably wouldn't be a bad idea....

    Also, I should probably change the fonts around so that they are more
    readable when the display is run at a higher resolution.

    As far as colors go, the reason that I didn't do a continuous variation is
    just a personal preference thing--it's hard for me to tell what flux density
    a color maps to if there are too many levels. With a finite number of
    levels, I can also pick the contour colors so that they don't interfere too
    badly with the colors that are used for rendering the other things in the
    geometry. N.B.--24 bit color is no longer actually a requirement. Things
    should be ok in 16 bit, and you can run it in 256, although the colors then
    tend to get dithered.

    Keith had good answers for the other points.

    Dave.
