diagonal text is kinky, Ian's request

auto connection using A* module http://search.cpan.org/~acdalton/AI-Pathfinding-AStar-0.10/
	- orthogonal or orthogonal and diagonal arrows
	- add get_cost_map to base Asciio
		- get_cost_map can also be implemented in draw in sub classes
	- connectors and elements could have different costs


Optimize the connection optimizer
	- no optimization needed for unchanged objects
		- asciio must keep track of changed objects
			- but we must not be intruisive
				- md5 ??

re-parsable asciio output with minimal data

	Path finding, see ISBN 2550-0124977820

add actions:
	- select all elements connected to currently selected element(s)
	- select all elemet connected to the element under the pointer
	- expend selection level with '+', also implement '-', '*', ...

	- optimize current arrow (A* pathfinder)
	- click + key on arrow adds a 'flex' point

what's new section

night colors don't change the ruler colors

? generate "nice looking" graph
	- interface to ditaa
	- HTML document?!

copy to clipboard removes empty lines at the begining of the buffer

two section arrow middle connector keeps horizontal with linked element
	this would reduce the amount of changes that need to be done manually

Curses UI

tutorial

add offset input to multiple element creation window

slide mode
	accept a directory as input
		show slides based on sort order or order.slide.txt
	allow saving of modified slides
	allow deletion and insertion of slides
		what if the slides are under git control?
	extra window to show slide order and modify it (and the slides maybe)
	extra slide menu (through actions)
		open
		save
		insert
		delete
	
arrow menu not working

document what ascii_events should contain
	links to gtk doc
	should the content itself be defined in the derived class?

split into two distributions?
	=> easier for those who want to build another interface

setup/actions manipulating asciio object directely move to asciio

transparent background for cmd output
	width > spaces == transparent
	spaces => transparent
	0 => transparent
	
merge arrows and split arrow

arrow merge object
	like a single character text but nicer to use with  arrows
	or merge arrow connections directely (weld them together)
	
multi-ended connectors
	add remove end from multi ended connectors

start and end connectors should have different colors

copy elements to the system clipboard to allow copies between instances

handle multiple versions with one of the following mechanisms:
	- embed git::PurePerl 
	- use PAR 
	- multiple directories

Display version somewhere

connected, non auto-connect, arrows loose their connection if the connectee is resized
	=> this is because resize doesn't keep the connection. The 
		canonizer reconnects elements but non auto-connect objects are not handled by the canonizer
		
		=> make canonizer re connect to the same place instead for changing the connector
		
magnet object for ESD

reload color options after loading file
	display_grid + element_backgound_color
	
search for stripe class in the setup directory
	or list the directories in the setup
	or add the directory as setup data and 'use lib'
	
let actions load stencils

forward KB + mouse events to stripes objects
	
table object
	bulleted lists and otherwise formatted text

record box object

save as pdf and printing

more than one resize handle

zoom on pointer
	#not ctl to zoom
	panning
	scrollbars
	
autosave

connector grouping

cancel button in editing windows

handle unicode (remove write_file)

now arrow can match inside a box, moving an arrow around has become more tricky
	=> do not connect if both ends are unconnected and arrow is being moved

move action constants to module

optimize do_stack serialization
	# use bzip2
	=> diff + compress
		# tests done
		must have a reverse diff that can patch both ways or it's not worth it
		
Management mode
	=> make ascii look like not ascii
		=> use ANSI X3.64
		
connections connected to a start and an end connector are displayed with warning color
	move to display plugins
	=> how do we handle double pointed arrows?

	=> this could be handled by the box object
		- the box object is asked to match a connector
		- the box object can dynamically create a connector
		- if the box object is resized, the connectors can be moved
			the connectors can remember their position if the
			box object is resized again
		- new connection should connect new connectors
			=> we need to know who we are connecting to

	=> or this could be done by the asciio object
		- asciio asks the box to add a connection
			this let ascioo decide where they should be placed instead for 
			deciding it's around the box
		- the user can add connectors with the same mechanism
		- the connector must be handled when resizing the box object
			by the box object or by the connector itself
