+1. No, VS Code is an unusable resource hog for me, I don't think you would gain sthg in trying the plugin again, the last releases were not full of changes.

Lem is remarkably featureful and usable for CL development though! Both its ncurses and SDL2 frontends. I only miss a couple keys from Slime: C-c C-y (print the function the cursor is on to the REPL), C-c ~ (sync the REPL with the current package (namespace)), then a better imenu, and that's it. Simple git support is available for power users too 8-)
