Neovim

Hi all! I installed nvim and completed the tutorial. I have been using CLion, PyCharm, IntelliJ IDEA, and VSCode. I primarily use an Ubuntu OS. I am open to a different distro.

When I tried to configure VSCode to allow me to use C++, Python, Java, and Assembly on one IDE it became unstable. Can nvim handle that?

Where do I go to figure how to customize this thing? For example, I don't know what I should be installing for basic linting (I'm still a student). Do I need different modules for each language? Any resources would be most appreciated.

Thank you!
