I agree with this; as Kevin Walzer already pointed out, the Tkdnd module
is nice for DnD within your application, but for "real" DnD you need
George Petasis tkdnd library, which unforunately supports only drops on
unix. In fact there used to be an earlier version of this tkdnd library,
where drag *and* drop worked on unix, which unfortunately is not being
maintained any longer.

If you don't need a themed one, you can use the Pmw.ScrolledFrame or the
Tix.ScrolledWidget, which is included in the standard library and even
easier to use than its Pmw counterpart (we've had this topic earlier here,
I admit that I totally forgot about Tix :), see this small example:
from Tix import *
r = Tk()
sw = ScrolledWindow(r)
for x in range(30):
for y in range(20):
Entry(sw.subwidget('window'), bd=0, highlightthickness=1,
I agree with you though, that it would be nice to have scrolled widgets
within standard Tk.
A few other things I miss from Tkinter:
* support for image formats other than gif
* text rotation
The Tk-8.6 beta release however adds a -rotate option to the canvas text
item and support for png images, so these issues will be resolved soon :)
* built-in tooltips were also nice, I'd love to be able to do
Button(master, text='foo', tooltip='bar'...)
* a decent html widget
* on unix some dialogs (file dialog, color chooser...) could be improved
