Yes, thats what I meant.

jep, that would be nice, but not terribly important right
now. Adapting some other lens calibration software might be the way to
go, just let the user take a few pictures of a chessboard and the
lens parameters should be estimated. (obviously its not perfect,
because the focus setting is probably when taking the chessboard pics.)

I see no fundamental difference (except that you can probably get away
without correcting smaller errors like lens distortion.). the
relationship between two images need to be estimated as well, before
the images can be stitched.

it is also called H and V control points. PTOptimizer can optimize x
and y differences or just x or y of the control points.

PTGui has a nice realtime view/editor of the stitched image, maybe
that would be a nice thing to have too. Having lots of small
thumbnails in the image list is (imho) not needed, because they are so
small that its hard get useful info from them.

Well, maybe some buttons could be still useful ;), like the delete
button.

yep, a advaced mode would be definately nice. any idea where the line
between simple and advanced mode should be drawn?
simple = person doesn't need to know how the PT tools work internally,
         for example linking of parameters is hidden behind some Lens
         interface that also allows the user to specify the image
         origin (digicam, scanned photo etc) and implicitly sets the
         right links.

advanced = export most options directly, for example linking etc.

yep, might be interesting for the expert.

I personally do not want to change the script, the GUI should
support all the features I need :) (*dreaming*)
