Thanks for developing this nice tool. I would like to ask you one question where does your plugin keeps its options/configuration? I mean Registry or some local file? I really need your answer. Thanks in advance.
P.S. Also I can report a bug, that I think i found. If the path to Notepad++ config directory (in %APPDATA%) contains non-English letters your, plugin cant create script in that folder.
The options and configuration are stored in PythonScript.cnf (might be a different extension sorry, I can't remember exactly) in %APPDATA%\notepad++\plugins\config (assuming you're using an appdata configuration).
Extended characters in paths should be supported from 0.9.2 onwards - are you using the latest version, and the unicode version? Can you tell me the output you get from the console when you try it?
