It will be good to make easier translation with com_association
my light idea is to add a tranlation button in editing view in toolbar (only if plugin language is enable) :

• article
• menu
• contact
• module

it can launch com_associations with context variable
like
itemtype=com_content.article
id=12
for a content with id 12
the workflow can be more simplier for translation !
After maybe need to load this in same page OR in modal ...
What do think about this ?
