Master password
Application now allows user to save connection information. It also allows saving password for saved connection which is very bad idea without encrypting the saved password. This means the database password is available for anyone having physical or virtual access to the hard-drive. Usual way to solve this problem is using master password (like password managers etc. do). Master password is easy to implement but very useful feature so you don't need to copy-paste the database passwords from separate password manager. This might not be suitable for all but I suppose nice feature for many.
