Subject field and message filed should share spell checking
Feature Summary
Currently, the subject field and the message field have different spell checking approaches:
- The subject field allows you to only select one language (out of the installed locales?) at a time to check against
- The message filed allows you to select multiple languages to check against (also out of the installed locales?)
How would you like it to work
I would remove the menu for the subject field and apply the spell checking from the message field also to the subject field.
