Need to uninstall a built-in plugin?

This question is asked so often here lately, someone should make a tutorial.

You need to add Local Storage plugin to your project, and manually update all actions and events - replace WebStorage with Local Storage. After that you can remove WebStorage from the project.

Note, that Local Storage works differently, read the documentation carefully, and check the official template:
