1) That's the beauty of Android, there are endless customizations. I too have mine setup the exact way I like it.
2) How ironic, after months of trying different roms to see what I liked best I'm also running 5.4.1.
In my case I like em lean and mean. Fast and free, so I decided I would put the bare minimum number of apps. Only the ones I use daily. A solid color static background, I like it to look uncluttered.
Now this baby is so fast, it nearly keeps up with my Galaxy S2. If I had not witnessed it myself, I wouldn't believe it.
What really makes me smile is to think of all the impatient angry Captivate users that bashed this phone so constantly. There's no question there's a lot of people that have done what you and I have, _without_ all the complaining...
Ironically this is one of the oldest Androids I have, and if not for my Nexus S, and SGS2, I'd rate this one at the top.
Nothing beats patience perseverance and an open mind. Never did I think it would be this good. I simply had the desire to learn the OS, and see how far I could go.
Rarely do I get attached to tech, but this ones a real keeper.
Cheers
