Need your opinion for the portable version

[Admini]

Is it possible that a portable version Cent did not create directory?
%APPDATA%\CentBrowser\User Data\Crashpad (in old versions Crash Reports)
For example, to move it to the user profile.

Also, not create registry keys:
HKCU\SOFTWARE\CentBrowser
HKCU\SOFTWARE\Chromium
Or delete them when you exit browser.

Cause: Every time, after work on another computer, I have to cleaned it manually.

These are default behavior of Chrome, we should better keep them as is, otherwise we will have more work to do during upgrade.
The two registry keys are used to record status of the browser, window position, last used profile, etc.
These information are not related to any privacy.You can just leave them alone.
