Lately I worked about application performance. I did a lot of improvements, but it is not a subject of this post.
I like to announce that server side application is working from now at http://chromerestclient.appspot.com/
After you log in you can view all data that you've sent to server and delete it if you need.
On this site you can remove all your data as well (including connection to your Google account).
If you have any suggestions write email to me or create issue ticket at http://code.google.com/p/chrome-rest-client/issues/list
