Hi,
First, thanks for the release of version 5. This is a real improvement from previous version for the interface.
I have update to v5.1 which is faster than v5.0 for big database.
I have a small note about the facility that was present in v4.3: the ease to access entries just by typing the first letter of Author name/Journal name.
Does it disappear with version 5?
Thanks anyway 
Guillaume
