Two things have made my work easier lately:

1. colourcolumn in Vim - nothing new, but incredibly practical.

2. a function I built into my own browser. I don't know if something like this already exists in other browsers, but I've never come across it before. I would describe it as "user-defined protocols", even if that's not quite the right word.

For example, you write the following in your configuration file:


And if I now enter ddg://foobar in the address bar, it searches for "foobar" because the text is simply appended to the URL specified in the configuration. This makes it possible to forward gopher and gemini URLs to an HTTP proxy, for example.
