Group
	Mac OS X: NSBox
		container_darwin.m: figure out if our setFrameSize: thing applies to resizing the groupbox as well
Control
	Enable()
	Disable()
Table
	more column types: "// As such, a Table renders a []struct{...} where each field of the struct can be a string, a number, an image, or a checkbox."
		table_darwin.m: constructor
		table_unix.c: goTableModel_get_column_type(), goTableModel_get_value()
	multiple selection
	figure out if we can safely refresh view during Unlock() regardless of calling goroutine
	document header behavior in general comment
	add functions for header manipulation
Tab
	// [TODO if each tab of your Tab is going to have the same content Controls, then use LikeTab instead, to conserve resources]
	Delete()
		// Delete removes the given tab.
		// It panics if index is out of range.
		// After Delete(), the effect of accessing the Control of the deleted tab or any of its children is undefned. [TODO reword?]
	investigate close buttons (especially for LikeTab)
Area
	Repaint(rect image.Rectangle)
	keyboard scrolling
		GTK+ port: our_area_focus_callback() has something to do with it
	OpenTextFieldAt() and OpenTextAreaAt() to allow editing of text from within Areas
Tree
	Mac OS X: make sure newScrollView() has the correct parameters for Table and Tree (and that Area has the appropriate ones from both + its own no border)
TextArea
	Mac OS X: be sure to call disableAutocorrect()
Mac OS X
	label alignment
		// in the other case, the most correct thing would be for Label to be aligned to the alignment rect, but I can't get this working, and it looks fine as it is anyway
	other controls
		same rules? checkboxes seem damning...
	ok in general
		spacing applies to alignment rects
			will conflict with Stack/Grid precalculation
			unless we resize the control and move it around to suit
		Tabs seem to have differnt margin rules
			need to check padding rules within Tabs
	activateIgnoringOtherApps: and command line programs: evaluate just how much it will matter

TextField
		text alignment (think labels and checkboxes) may be a perpetual problem though
	add events (figure out which of the following are appropriate: changed, enter pressed)
	provide some facility to mark invalid values
	figure out numerics because you CAN paste into numeric boxes on Windows and GTK+ has no built-in number validator as far as I know
Stack, Grid
	method calls should trigger re-layout of windows
default buttons
	figure out how they interact with Areas (especially on GTK+, where GtkEntry somehow has special handling for this)
in general
	new moving stack and future moving heap make package ui a pain in general
dialog boxes
	find out if Stop has an effect before a dialog box function returns

so I don't forget, some TODOs:
windows
	- backgrounds are not transparent
	- tab order is backwards
	- flicker ahoy
	- not all controls are transparent
gtk+
	- Area: figure out how Enter is processed in Entry
		https://git.gnome.org/browse/gtk+/tree/gtk/gtkwindow.c#n1229
gtk+, mac os x
	- figure out how dialogs and Areas work together
		- once that is done, document the behavior of Areas
all
	- make spaced settable somehow
