When trying to use html tidy an error is reported 'Unable to find libTidy.dll'
in the system path or %PATH%\Notepad++Portable\App\Notepad++\plugins\Config\NppTextFXA\libTidy.dll' This is simply due to the files not being in the indicated folder. Move the files to the folder indicated in the error msg and you are good to go.
Don't know if this is a problem with Portable version or if it is a general bug but
it would be good if it could be fixed so less tech savvy individuals could use it.
Best regards, and my compliments on maintaining such a superb site.
