Well, wxPython itself is largely the work of a single person, but I
doubt that many consider that a reason to avoid it.

As far as your comment about 'slowing down' the app, I've found that
Dabo and pure-wxPython apps run indistinguishably. Perhaps there are
some microseconds of extra processing, but I sure haven't noticed it.
And I don't think that the comment about installing another package is
fair; *anything* outside of the standard distribution requires that,
and Dabo is no more difficult than copying to site-packages.

I do agree about the documentation aspect of Dabo, though. The authors
have put together some basic stuff to get you started, but have chosen
to focus their time on continued development for the time being. But
having said that, I found that Dabo uses a very consistent syntax, and
was no more difficult to pick up than Python itself. With wxPython, I
constantly had to refer to the docs, as every class did things
slightly differently. For example, many controls have some text
associated with them. Depending on the control, you need to call
SetText(), SetLabel(), SetBitmapLabel(), SetTitle(), etc. Dabo wrapped
all of these controls so that the identifying text for each is
controlled by a single property: Caption. In any Dabo control,
executing ctl.Caption="Something" will change its associated text.
This sort of consistency removes the need to constantly refer to
documentation in order to write your code.
