I hope to have the option to start with the incognito mode homepage. It is also inconvenient that I cannot select all when copying text, so I hope to add this functionality. If possible, please add support for custom user agent and custom search engines (for using by entering the website URL). When using the auto-wrap mode, some URLs with long strings of base64 letters do not wrap properly, so please fix this. The ad-blocking plugin sometimes doesn't work, so please add support for AdGuard.
