I can recommend my own plugin NavigateTo. More information: https://github.com/young-developer/nppNavigateTo/blob/master/README.md
Navigate To is a new and efficient way to quickly navigate between tabs(files) in your Notepad++. It allows you to search for a symbol or filename, filepath by matching against a keyword you type in, and get a real time preview while going through the search results by Shift key. And YES indeed you can uncheck the Multi-line option, in the Preferences > General > Tab Bar zone because you don’t need the multi-lines tab feature anymore :)
