    Andrew's list:
    ==============

    - Add a new check box to Prefs > Layer: "Automatically show/hide layer bar".
      If ticked then layer bar is automatically shown whenever the number of
      layers becomes > 1, and automatically hidden when the number drops to 1.
      Only need to check in a few places (esp. after a script ends).

    - Auto stop script if it creates too many temp files (for undo).
      This can happen if a long-running script doesn't call new/open
      when it probably should.  See my email to Nathaniel with subject
      "Re: Golly methuselah search script".

    - Stop generating if pattern becomes empty, constant or p2 (qlife only)
      and display suitable message in status bar.  Or maybe just add
      Gabriel's oscillation detection as an option (see oscar.py).

    - Allow non-rectangular (and disjoint) selections.

    - Add simple methuselah/spaceship/osc/still-life searches as in LifeLab???

    - Add case studies to BUILD file: how to add a new menu item, how to add
      a new algorithm, etc.

    Tom's list:
    ===========

    File I/O

    - Have hlifealgo .mc compatible with ghashbase .mc
    - Generalized RLE in MC?

    Algos

    - Unzoom color merging
    - Better status reports (% of hashtable full)

    Scripting

    - Tape construction script for replicator

    Samples

    - Small JVN examples

    Fun

    - htreebase
    - hgridbase (finite universe; torus, etc.)
    - allow (base) x (slow) algorithm "multiplication"
    - pluggability of externally-defined algos
    - python slowcalc callbacks
    - cache of slowcalc
    - generational gc
    - 32-bit indexed hashlife on 64-bit platforms

    Other

    - Improve batchmode.

    - Fix qlifealgo::lowerRightPixel to prevent off-by-one error when
      selecting large pattern like caterpillar.

    User suggestions:
    =================

    Nick Gotts:
    - Need a way to copy exact gen/pop counts to clipboard.
      [No longer necessary now that a script can get this info.]

    Jason Summers:
    - For better viewing of patterns that move, have a way to automatically
      move the view X cells horizontally and Y cells vertically every Z gens.
      [Could be done quite easily via a script that prompts for X,Y,Z.]
    - Allow diagonal selection rectangles.

    Dave Greene:
    - Provide a way to click-and-drag a selection to move it around.
    - Make page and arrow scrolling amounts configurable (in Prefs > View).
    - Add a getview() script command that returns current viewport rect
      and a setview(rect) command to change viewport size and location.
    - Make info window a floating window and keep it open (but update
      its contents) when user loads another pattern.

    H. Koenig:
    - Multiple windows.  [No real need now that we have multiple layers.]

    Gabriel Nivasch:
    - Add a Default button to each Preferences pane (at bottom left?).

    Bill Gosper:
    - Modify info window so it can be used to edit and save comments.
    - For scales > 1:1 make the pixel color depend on lg(# of ones in it).

    Brice Due:
    - Provide MCell-like editing capabilities.
    - Provide a thumbnail option as an alternative to tiled layers;
      ie. the current layer would be displayed in a large "focal" viewport.
      All layers would be displayed as small, active thumbnails (at left
      or top edge of focal viewport, depending on aspect ratio?).
    - Allow mc files to set step base and/or exponent via comment line like
      #X stepbase=8 stepexp=3
      [No need now that zip files can contain pattern + script?]

    Tim Hutton:
    - Add a script command to save comments in a pattern file.  Add optional
      param to existing save() command?

    William R. Buckley:
    - Provide an option to increase spacing between buttons.

    Dean Hickerson:
    - Make Duplicate Layer faster by writing current pattern to temp file
      and reading it into new layer.

    tod222:
    - Allow a command line argument (-minimize?) to start up with the
      main window in minimized state.  Should be possible in OnInit.
