Google Canary was designed so that users can contribute to the development of a better version of Chrome. You can try everything you want in order to introduce future changes in the updates of the main browser.
You have to keep in mind that the user may find this version a little unstable since it is prone to breakdowns, but that won't affect your stable version of Google Chrome at any time. You can have both versions installed at the same time and there won't be any problems between them.
Another important feature is that developers can work with new functions and Chrome APIs, in addition to relying on all the features that are available in the normal version, including Flash and PDF reader.
