I uploaded a filename autocompletion plugin on github. It completes your typed filepath, based on files found within your project. Filepaths are inserted relative or absolute, depending on your current scope or command. There is a similar plugin AutoFileName available, but it uses filesystem exploration instead of search. Since i don't like remembering things but having fast results, i prefer FuzzyFilePath.
I am curious if someone else might find this helpful and would be glad to get some Feedback.
Enjoy your Weekend.
