Description
It would be very nice if the plug-in could find the LibreOffice or Firefox dictionaries that are already installed on the pc. These products use Hunspell. I think quite some N++ users also have one of these products installed.
LibreOffice: C:\Program Files (x86)\LibreOffice 4.0\share\extensions\dict-*\
Firefox dictionaries are a bit more complex to find because the default language (Dutch in my case) comes with the browser and is in C:\Program Files (x86)\Mozilla Firefox\dictionaries, but the languages I added (like English) are in the user profile: C:\Users\Frank\AppData\Roaming\Mozilla\Firefox\Profiles\6tujqnz2.default\extensions\en-US@dictionaries.addons.mozilla.org\dictionaries
I assume Thunderbird works similar, don't know because I don't use Thunderbird.
On my old pc at home I have 32-bit XP, so here they are in the normal C:\Program Files\ directory. I don't know where the words added to the user dictionary are stored, but remember that not everybody can write in program files directories.
According to http://en.wikipedia.org/wiki/Hunspell Chrome uses Hunspell as well, but in my Chrome directory are *.bdic dictionaries. Found http://dev.chromium.org/developers/how-tos/editing-the-spell-checking-dictionaries where they say that *.bdic are their own optimized hunspell dictionaries, so they won't help your plug-in.
