Thank you for the suggestion - a search bar is planned and there is a GitHub issue for it here: https://github.com/samerton/Nameless-Resources/issues/78
Unfortunately there is no support for other plugins yet, hopefully we can add support in the future.
Yes exactly - all you need to do is make sure the files are in the correct location for the domain and change the hostname value in the file core/config.php
Yes this is possible, and there is an example web.config file provided: https://github.com/NamelessMC/Nameless/blob/develop/web.config.example
Unfortunately none of the team use IIS so it is unlikely that we will be able to provide you with support for the web server configuration.

@MeoBaka Do you see the same issue with the Default Revamp template (if you are not already using it)?
