I have a suggestion that most of the users may like. We all know that most of the people hate the new Microsoft design. I think it would be GREAT if you add something in the settings that can change the WHOLE Skype layout. (Ringtones, design, settings, UI, etc.)
For example I have 3 layouts to choose from:
Microsoft Design (Default)
Skype 6 Design (Classic)
First ever Skype version (Old)
If I choose Microsoft Design nothing would change as this will be the default one.
If I choose the Skype 6 Design, the app would change EVERYTHING so the Skype looks and acts like Skype 6. For example we would be able to change all of our sounds again. And everything from Skype 6.
Same goes for First version.
Please consider this suggestion as I think very much people will return to using Skype, I will post about this everywhere (if you accept it) Twitter, Instagram, etc.
Personally, I love the Microsoft Skype more, but most users prefer Classic.
My bad, I meant Skype 7, not Skype 6.
