Capitalization:

    For any visible text used within KiCad, follow recommendations here:

    http://library.gnome.org/devel/hig-book/2.20/design-text-labels.html.en#layout-capitalization

    This applies to all Menus, Titles, Labels, Tooltips, Buttons, etc.

    http://developer.gnome.org/hig-book/stable/design-text-labels.html.en

    in the "Capitalization" section.  This applies to all Menus, Titles,

    Labels, Tooltips, Buttons, etc.

    The capitalization for the application names is KiCad, Eeschema, CvPcb,

    GerbView, and Pcbnew.  All strings that have application names that are

    Follow the recommendations here:

    paying particular attention to "initial focus", "sensible default values",

    "default buttons", ESC key termination.  Please note that the escape key

    termination only works properly if there is a dialog button defined with

 i) FPID

 ii) footprint alone since most old netlists don't have nicknames in them.

e) Replace MODULE::m_LibRef which is a wxString with FPID.  FPID supports

   the footprint name only which is backwards compatible with the current

   design.

f) On the first time an empty global footprint table is encountered, add

   standard KiCad and user libraries not located in the project directory

   or any of it's sub-directories to the global footprint library table.

g) When a project is opened and the project footprint library table is

   empty, add any user library that is located in the project path or any

   of it's sub-directories to the project footprint library table.

h) When populating the footprint library tables, use the library  file name

   without the extension as the FPID nickname.  When duplicate names exist,

   append an incremental integer to the nickname so that the second logic

   libraries FPID nickname becomes logic1.  Assign FPID library nicknames

   to each MODULE based on the legacy library search order when loading an

   existing board that does not have fully defined MODULE FPIDs.

i) Add check for KISYSMOD environment variable, on Pcbnew and CvPcb start up

   and set it to the known directory of the default KiCad footprint libraries.

   The code should look something like:

{

    const char* envar;

    envar = getenv( "KISYSMOD" );

    if( !envar )

    {

        envvar = knownDirOfSysMods;

        setenv( "KISYSMOD", envar );

    }

}

These i) and ii) merge into one if footprint alone is a valid FPID.

Incorporate any environment variable in the the uri expansion using:

const wxString FP_LIB_TABLE::ExpandSubtitutions( const wxString aString )

    /**

     * Function RedrawScreen2

     * puts the crosshair back to the screen position it had before zooming

     * @param beforePos The screen position of the crosshair before zooming

     * @param posBefore screen position of the crosshair before zooming

     */

    void RedrawScreen2( const wxPoint& posBefore );

    /// This is also the last used netclass after starting a track.

    wxString                m_currentNetClassName;

    /// Index for #m_ViaSizeList to select the current via size.

    /// Index for #m_ViasDimensionsList to select the current via size.

    /// 0 is the index selection of the default value Netclass

    unsigned                m_viaSizeIndex;
