The Studio Launcher is redesigned in UNA 10, adding a new feature we call Switcher, which tracks the apps you've opened in Studio and shows them in successive order in the header. THis way you can switch between a few apps you used most recently without having to find them in the Launcher. Really helps when you need to switch between, say, Forms, Designer and Polyglot frequently.
Please try to work on the injection too. Some of us have problem adding codes to the <head> through INJECTION at studio. Personally, I've not been able to implement adsense on my website because the Injection won't load in the code. It's even more depressing when you want to add other web master codes too. Like Onesignal and all.
