    This file is used as a scratch pad by developers.  It is a list of known
issues that need to be addressed.  Divided into, things that will prevent
release, and longer term bugs.

Release Critical

Please fix https://bugs.launchpad.net/ubuntu/+source/gtk-doc/+bug/77138

Plans
-----
    1) Format and number match rewrite
	: When applying a currency symbol we need to store the NON-localized id.
	: hour month and year format strings need to be internationalized.
	    eg tt:ss instead of hh:ss for other locales.
	: formats with AM/PM need to be internationalized.
	: We do not format fractional seconds correctly.	(DONE)
	: Parsing should handle embedded strings
	: It incorrectly accepts mmm:ss as some sort of minute spec.
	: Consider adding "%" to entry text when typing a text with a percentage
	  format.  (I.e., user has "44%" in cell and presses "5" -- that causes
	"5%" to be shown the cursor between "5" and "%".)

    2) GOActionComboText
	2.1) stub						(DONE)	
	2.2) Move to TreeModel to simplify sharing
	2.3) Support custom menu item
    3) Plugin Framework
	3.1) "De-activate all" should take the dependency tree
	    into account and handle the python loader last.
	- i18n support for third-party plugins.
	- Add extra info (authors, etc.) to XML file.
	- Beautify ErrorInfo dialog (it's ugly).
	- Mark plugin as "broken" if deactivation failed.
	3.2) pluginize paste types
	3.3) plugin manager needs dependency tracking.  (Deactivate
	  all python plugins before the python loader, for example.)

Misc things to fix
------------------

	: Open guru, click on forward, then back. Now		<--------> 
	navigating through plot list is very slow. That's 
	because at each object addition/removal in object tree,
       	an object editor is created.

	: Current GogGrid object is not used for grid display.	(FIXED)
	We should rename it to GogBackplane, GogWall or 
	GogBackground.

	: Markers with non solid fill color are displayed 
	without filling for some shapes.			(FIXED)

Ideas
-----
    - Dimension choser as label in chart
    - Use Legend to manipulate data
	- edit style of various series
	- Add/remove dimensions
    - select items in a plot
    - Matrix feature to replicate a group of plots using different slices of
      data.  eg XY for age x salary, with distinct chart for M and F
    - Add 'group' button to the data editors to pull up a context menu that
      allows for grouping / filtering

    - filter/group routines from autofilter into goffice for charts and pivots
    - concentric ring plots that aggregate inwards and optionally fold outer
      rings/segments.
