Android Question What does the "Download SDK" button do in the SDK Manager?

Will be removed. Over time the approach with the sdk manager has changed. The sdk manager is less important now and only used to add esoteric resources that are needed from time to time and to access the emulator. The sdk itself with most relevant components is downloaded as two packages.

Actually, after checking the source code I see that it only opens the browser with b4a instructions page, so it will be kept.

Maybe reword the button to "SDK Download Instructions" so it won't be so mysterious?
