Short answer: you need to use the Glow look (More -> Config -> Options -> Global Display Version) to get the newer, wider tabs. This will change all your controls to the newest version. You can then change each control to the old version, but you shouldn't do that. The new version is hard to get used to, but it really is superior in every way...
One huge advantage: Display Zero (part of the EFP, so you need to buy that)
