Create Issue

Note: use code-insiders --transient for a fresh startup.

Review the new chat.disableAIFeatures setting and make sure you can understand.

Test without extensions

• do not have Copilot installed
• toggle the setting between its states and validate AI UI hides and shows
• verify this is persisted between restarts
• verify you can configure this on a per-workspace level having AI UI visible selectively

Test with extensions

• install Copilot
• toggle the setting between its states and validate AI UI hides and shows
• verify that toggling also updates the enablement state of the Copilot extensions
• verify you can configure this on a per-workspace level having AI UI visible selectively and verify that in this case extension enablement only applies per-workspace

Test special cases

• set chat.disableAIFeatures to true but install Copilot manually via extensions view, verify the AI UI appears and chat.disableAIFeatures flips to false
• set chat.disableAIFeatures to false, install Copilot, quit the app and use an external editor to change chat.disableAIFeatures to true, start the app and verify the Copilot extensions disable
