One of only about three things I miss from switching away from Windows, is that I now have to use Sublime instead of Notepad++. It was just so much better at dealing with large files and batch operations, which are a priority for my work. But Sublime has beat everything else I have tried out on Linux, and obviously has features Notepad++ does not.
Fleet is supposed to be this lightweight editor but unless it can beat sublime at startup, it's not.
