Nvim is superior, plus, plugins can help avoid those problems. Barbar alone will let you know if you have multiple buffers open, because it will make tabs. Chadtree is cool too for browsing files from nvim, so you can open files in new buffers from a browser and use the standard buffer to cut and paste between buffers without having to use xclip ("+yy).

Ranger is another to die for tool. Nothing compares. I modified the rc so that I can open files on specific desktops (using nohup, so the opened process isn't a child process of ranger — so I can close ranger if needed). Shift+O+<nu
> uses mime, shift+E+<num> uses nvim. I can also compile pdfs directly from ranger and send files to my phone. Plus ranger itself can have buffers, alt+<number> opens a new buffer and files can be copied and pasted between them. And since ranger runs in terminal, you can have multiple terminal buffers too.

Linux isn't a joke is you know how to use it. It's a beast. Plus, it makes my wife wet when I get shit done. 😏
