I have used SD 2 beta 3 yesterday I feel lots of bugs has been solved, but you need some change in interface.
1) Remove those unnecessary scroll bars and separators they are making interface cluttered.
2)Allow interface to maximize, maximize button is disabled.
3)Change tray icon and shortcut icon to shield shape icon with some glassy effects, come on SD team I have used almost all security softwares. Now don't you want this software to look like professional software rather than school project.
4)make an option to hide tips panel it destroys looks of SD.
Since this software has lots of potential n its mine favorite I want to contribute
i am with you n thank you for providing this little gem good work SD team keep it up.
