Yesterday i was hacking a bit in Anjuta and I added a new feature.
Now you can activate the brace autocompletion. What this mean?
It means that when you enter a '(' '[' " you are going to have the same behaviour than in eclipse. Anjuta it is going to add the ')' ']' or " and if for example you have (|) (| it is the cursor position and you add a ')' the ')' it is going to be skipped.
