A simple website, that will be a personal alternative to the startpages, provided by current web browsers.
It is possible to access it online here: https://doxanthropos.github.io/startpage/
I use the Open With browser extension to open websites in different programmes and one of the options, that I have configured is to open in a text editor. This obviously only works with html files that are accessed from the file system and not from the web, so I have set my browsers starting page to be the local version.
