Application Logging
Make application logging in all applications an option to enable or disable. Always having the application generating logs not only makes the application somewhat insecure, but it also generates a lot of application bloat and overhead. This would allow the applications to aways run a peak performance and not slow the applications down at launch or other areas of the application.
I especially see this being beneficial in the VPN app, over time the application become slow and somewhat unresponsive. Uninstalling the app, inproves the startup perfromance and over all performance of the application.
If a support case is needed, I would enable logging, reproduce the issue and send the logs. Otherwise they would be disabled and should be disabled by default.
