sangohan / settings.jsonc
Created May 15, 2023 10:18 — forked from hyperupcall/settings.jsonc
VSCode config to disable popular extensions' annoyances (telemetry, notifications, welcome pages, etc.)
// I'm tired of extensions that automatically:
// - show welcome pages / walkthroughs
// - show release notes
// - send telemetry
// - recommend things
//
// This disables all of that stuff.
// If you have more config, leave a comment so I can add it!!
