Expansion Opera: VKontakte Informer

I have been developing applications for the social network VKontakte for a long time. But I always wanted to try some new API. I didn’t want to study the API of other social networks, so I decided to try to develop an extension for Oper, in which there are extensions since version 11 .

I looked at what extensions are already there, about 350 of them so far (of which only 35 are in Russian), and decided to make my own.

An extension that will check messages, friend requests, invitations to groups / meetings, photo marks, etc. on the social network VKontakte.

Half the night I studied the API, I looked at examples of applications, but by 6 o'clock in the morning I realized that what I want to do will not work. But the next day after sitting a couple more hours made the first version of the application! At the moment it has already passed moderation and is available to all!

How it looks and works:



In the settings, you can select the update frequency, sound notification, etc.

Extension: VKontakte Informer
Browser: Opera 11+

IMPORTANT
The moderation of extensions for Opera is very tough! Every line of code is checked!
You can not worry about the safety of your password VKontakte.
In addition, everyone can check where and to which servers data is sent from the extension.

Thanks in advance to everyone who will test the extension.
Please leave comments on how the extension works and what errors occur, if any ...
