I don’t think AWS CloudShell should open in new tabs or switch regions for global services
When you have AWS CloudShell open and you navigate to a new tab, CloudShell gets opened in the new tab. This is strange, Now I have two tabs where I could potentially open the same file and it might be in different states in each tab.
CloudShell should remain open in the tab where it is currently in use but not be automatically opened in new tabs.
