To improve a huge number of features, it is necessary to integrate a local database into the extension.

This will allow the extension to store a large amount of information about the dialogs or blocked people. The data will be stored locally on the user's device, nothing will be transferred anywhere.

We need a fast, reliable and battle-tested solution. I'm thinking about https://github.com/jlongster/absurd-sql but there might be issues with reliability. Need to think.
