Ajax preview bubbles
Possibility to show the bubbles on hover over the post title.
I'm not willing to support that. Yes, it saves one click per entry but on the other hand it can – and I'm convinced it will – lead to many faulty operations, when users move the mouse cursor, pass over the titles of entries and opens numerous preview bubbles unintentionally.
We can/should add an option to the forum setting table to make this feature optional.
I am still not convinced but I am not the project leader. So I will not hold back this feature, even if I personally think, that it is a misfeature. So here is my go for the merge with an extension to make it an optional feature. Let's merge your code after the final 2.3.7-release.
