Rated 4 out of 5 stars

Nice add-on!
For merindol: remove *.aff and *.dic files which are symbolic links in /usr/share/myspell/dicts/.
(For example I had fr_BE, fr_CH, fr_CA .aff and .dic pointing to fr_FR.aff and .dic.)

This review is for a previous version of the add-on (1.0.1.1-signed.1-signed).
