How to create a new file from Finder's context menu?

Could you tell me how to add a menu item into Finder's contextual menu (the one I get when I Control-click in a folder)?

When I create a document or spreadsheet using LibreOffice, I usually run LibreOffice first and then choose Text documents, or I choose the item of LibreOffice's contextual menu from the Dock. But, the new document is not created under a specific folder. So I have to choose the folder and enter a name for the file to save.

I would like to create LibreOffice text documents or spreadsheets by using a menu item. It should create the documents under the folder I'm in.

This is a screenshot of the contextual menu when I press Control-click in folder.

Solution 1:

XtraFinder

Update 2021: This app requires you to disable System Integrity Protection in macOS, which is not recommended. Therefore, this cannot be recommended for normal users.

The free app XtraFinder gives you an option to add a New File entry to the contextual menu in Finder windows (amongst others, like opening a Terminal window):

You can manage the templates for files easily:

All you'd have to do is add an empty LibreOffice file in that template directory.
