1. version 188.8.131.52 what is its status BETA or RC?
2. Where and why in version 2.1 the button – change background color skins
3. Also in version 2.1, does not work the function of checking update of the new version and notifying it (for a show of seconds the message “This is the latest version available” appears) and everything and there is not even a button to download update
4. Is it possible to do so, following the new versions, as in the previous 1 and 2.0 version, to hide the activation field in the window field – the activation key itself, like the password in previous versions
