I use NimLime for syntax highlighting. In theory, it does other things such as error checking and auto-completion, but I've gotten any of that to work. I strongly suspect there is some undocumented setup involved. If you find more useful information, please let us all know.
(Of note: I run Sublime 3 under PopOS!, an Ubuntu variant.)
Welcome Marcone, the linter from sublimetext's NimLime plugin is based on nimsuggest, it can be made to work with some effort but NimLime is very usable without nimsuggest.
I've also used D a lot in the past, maybe you'll find https://github.com/timotheecour/D_vs_nim helpful in mapping concepts from D to nim (may be out of date, PR's welcome)
