**Query defined variables, i.e. get a list of currently defined variables. Bonus points if it could tell you if anything had changed since the last time you checked the variables (could also be done with signals).

**Make the links in the "Experimental GUI info" dialog box (the one that appears when the button "More Info" is pressed) clickable. They are not clickable in the 3.8.2-2 version (at least not on Windows 7).

== Implement a Qt widget for manipulating plots ==
Octave has had for some time a native OpenGL plotter. The plotter requires some user interaction for manipulating the plots, and it's been using fltk for quite some time. We want to replace this with Qt, so it fits better with the overall GUI look-and-feel and is easier to extend in the future.
[https://github.com/goffioul/QtHandles QtHandles] is a current work in progress integrating the octave OpenGL renderer plus good support for GUI elements (uicontrol, uimenu, uitoolbar...). This project may initially consists of integrating the existing QtHandles code base into Octave. Then if time permits, further improvements can be made to QtHandles.

* On 'imagesc' plots, report the matrix values also based on the mouse position, updating on mouse moving.

* Create a "getframe" function that receives a  a graphics handle and returns a 3D matrix from the graphics window associated with that handle.


* Add map-creating capabilities similar to the Matlab [http://www.mathworks.com/help/map/functionlist.html Mapping toolbox] for inclusion in the Octave Forge [https://sourceforge.net/p/octave/mapping mapping package].

One list is provided on the source for function __unimplemented.m__, subfunction missing_functions; it can be edited in the Octave GUI or browsed at [http://hg.savannah.gnu.org/hgweb/octave/file/default/scripts/help/__unimplemented__.m#l547].

Lists are also kept for the [[Image package|Image]], [[Mapping package|Mapping]], [[Optimization package|Optimization]], [[Signal package|Signal]], [[Splines package|Splines]], and [[Statistics package|Statistics]] packages.
Lists are also kept for [[:Category:Missing functions|several packages]].


It is also possible to look at existing [[Wikipedia:Free and open-source software|FOSS]] implementations, from FreeMat and Scilab (for more closely compatible languages) to R or Scipy or Julia (for less compatible versions).  Obviously, it is NOT OK to look at the Matlab implementation since this is not [[Wikipedia:Free software|free software]]!
