This is basic common sense. I have been using this method for as long as I can remember. You don't need special apps other than your simple text editor. Almost all modern terminal emulators recognise URLs. You can test this by hovering your mouse over a link in a text file -- The link get underlined. Ctrl-click opens the link in the default browser. Add new URLs with a little description or a few words as tags -- all free hand on the same line as the URL. Consider using Linux "less" as it allows you to search through thousands of URLs and find what you want in seconds. Ctrl-click and you are done.
