Topic from the last post read

I would like to make two suggestions:

• 
  
• When a user clicked on the link of a topic, the topic would be loaded from the last post read by that user. This would make it easier, because almost always have to guess which was the last post I read that particular topic.
• And the last would be first a doubt, you can add a Spellchecker the editor of IPB? For example add a French Spellchecker and now leaves it as default. If you do not have this option as the default, I would suggest it for future versions of IPB.

Thank you.
