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 :)
Copy NavigateTo.DLL to \plugins folder
Go to Settings > Import > Import Plugin(s)..
You can open plugin form under the “Plugins > Navigate To ” menu or use the keyboard shortcut “Ctrl + COMMA” to bring up the “Navigate To” dialog.
