Yes I did, first thing done.
You can see here « France » for Formats but actually it never stays in place, at next launch of BCC, it’s America there which comes back.
Also I have removed ( for the moment ) any other language else than French - only basic mandatory English remains.
I did not test long enough to see how or if it affects the system, keyboard mapping is expected azerty + french ( alt ).
BCC version :
ii budgie-control-center 1.0.1-2 amd64 utilities to configure the Budgie desktop
ii budgie-control-center-data 1.0.1-2 all configuration applets for Budgie - data files
Is there a way to « reset » BCC ?
