I type about equally in both my native language and English. Spellchecking is less important when using my native language but it would still be nice to have it - or at least to deactivate English spellchecking.
Is there an system wide plugin or at least any browser specific extension that would be smart enough to figure out in which language I'm typing and automatically switch to the according dictionary?
I'm using Google Chrome on OS X Snow Leopard.
