Context: TeXstudio 2.10.8 (hg 5844+:47f3e0323eb5+), Qt 4.8.6 R, on Linux Mageia 5) and "Package csquotes: \enquote{ }" is selected in menu Options → Configure TeXstudio → Editor → Replace Double quotes.
The first double quotes inserts \enquote{ and the second double quotes inserts }. That's annoying because:
Maybe better: the first double quotes doesn't insert anything, the second one inserts \enquote{} with the cursor between the braces.

au contraire! Personally, I am not such a fan of editors providing opening and closing bracket/braces at once. I write quite "linearly", and press, therefore, the closing mark as well. But just my 2 cent.
IMHO, providing opening and closing bracket/braces at once is a vital feature for a TeX editor: some many users, even not beginners, are puzzled because of a cryptic error due to a missing curly bracket somewhere in their document...
