Anything missing in Blackberry 10?

I use to have a Blackberry 8900 and 9700 that ran OS5 back in the day and loved it because I could customize a ton of stuff similar to Android but the lack of a good browser forced me to leave Blackberry behind for Windows Phone (I despise Android and IOS). Now with the release of the Z10 and Blackberry 10 my interest has been renewed, and I miss the red LED, :laughing: So is there any customization or settings missing from OS10 that was there in OS5? An example of this was when I traveled outside the country I could set it up so it never used the carrier APN allowing for the use of everything while roaming but never getting a huge cell phone bill because everything was running through RIMs servers. It was just crazy the amount of things I could change and the install of a different carriers update was simple so I didn't have to wait in hopes that my carrier would release the update like I do now. So can some of you new lucky OS10 owners give some inputs that would be great. Thank you ahead of time.
