<!-- ⚠️⚠️ Do Not Delete This! feature_request_template ⚠️⚠️ --> <!-- Please read our Rules of Conduct: https://opensource.microsoft.com/codeofconduct/ --> <!-- Please search existing issues to avoid creating duplicates. --> VS code version: 1.50.0, Linux Ubuntu <!-- Describe the feature you'd like. --> I would like to suggest an option in the settings to keep the old pattern of hide suggestion. If this already exist so I can't found it int the settings. It's very very very tedious and borring the suggestion window not hide like before, and this newer pattern of vscode not help (for me) in the edition. So, please, add some option in the next version to keep the old style of hide the window: press left or right and it go tothe holy from it came.
