DrPython is a highly customizable cross-platform ide to aid programming in Python. It was developed with teaching in mind, and has a clean, simple interface. It is written in Python, using wxPython as the gui.
Lots of work has been done, reworked several dialogs, tweaked the interface (now shows overtype, indentation informationin statusbar), and plugins (automatic install/uninstall scripts), and the toolbar (add drscripts, plugins, customize specific icons), and important bugfixes in find/replace, keyboard shortcuts, in general.
Plus Search In Files is now a plugin.
