Hey @zhouxinghong,

I don't think it's possible to remove toolbar entries (as a user). Adopters of the framework can choose to remove those toolbar items in their custom app, but the distributed Theia IDE app doesn't feature such a functionality.

@msujew It is recommended that users be allowed to hide unused buttons.

I know that VS Code offers the option to hide toolbar buttons:

But Theia doesn't right now. I've raised #14000 to track this.
