Sounds awesomely powerful - not since the development of John Harrison's clocks will navigation have taken such a great step forward :slight_smile:

Combining my original thoughts with yours and Charles, then. How
about the following? Allow the user to select the old style toolbar
from a config file, but the new toolbar would

  1) lose all the left, right, up down buttons, in favor of a single
     'hand' icon that allows you to move the view limits by 'grabbing
     them in the axes and moving them around. With x or y key pressed
     the pan motion will be contained to the respective axis. The
     mouse button which activates this in the axes should be easily
     configurable so as to not class with application developers.

  2) have a zoom in and zoom out button that work on both axis
     symmetrically unless the 'x' or 'y' modifier keys are pressed in
     which case work only on that axis. Allow similar functionality
     with the mouse in the axes, eg wheel mouse, as Charles suggested
     or mouse-3 as vtk interactor windows use. Then you could pan and
     zoom in an axes without ever removing your mouse from the axes
     lim.

  3) have a zoom rectangle tool that allows you to zoom to a selected
     rectangle, constrained to maintain axis ratio if CTRL is pressed

  4) have a zoom to data button that changes viewlim to incorporate
     entire dataset

  5) use the 'views' navigation with forward / mark / and back buttons
     that allows you to navigate between views

  6) lose the redraw button, obsolete

  7) have a savefig button which allows you to set the dpi, filename
     and backend, so you can output with ps, gd, or gtk backend

  8) close window unchanged.
