Configuration tips

Make project manager enumerating your git based projects:

"projectManager.git.baseFolders": ["/home/USERNAME/FOLDER","/home/USERNAME/ANOTHERFOLDER"]

Improving performance in the built in terminal (Tested on Ubuntu 18.04)

• Change the terminal rendering (Terminal › Integrated: Renderer Type) to canvas
• Start VS Code with code --ignore-gpu-blacklist

Toggle the terminal using a keybindings

{
    "key": "ctrl+[Backquote]",
    "command": "workbench.action.terminal.focus"
},
{
    "key": "ctrl+[Backquote]",
    "command": "workbench.action.focusActiveEditorGroup",
    "when": "terminalFocus"
},

Toggle maximized terminal

{
    "key": "ctrl+j",
    "command": "workbench.action.toggleMaximizedPanel"
},

Clear the terminal

{
    "key": "ctrl+l",
    "command": "workbench.debug.panel.action.clearReplAction"
}

Disable MS telemetry

"telemetry.enableTelemetry": false,
"telemetry.enableCrashReporter": false,

Require Guest approvals for Live Share

"liveshare.guestApprovalRequired": true,

Remove the minimap to get some better performance:

"editor.minimap.enabled": false,

Always open up new Window maximized

"window.newWindowDimensions": "maximized"

Recommended search exclusion:

    "**/.class": true,
    "**/.git": true,
    "**/.hg": true,
