Remove multiple application with same purpose to make distribution easy and leaner

I have seen there are to many application in Ubuntu with the same purpose. I am just listing some of them and update it latter.
1. Banshee as Default Audio-Video player, also Movie player also present, remove it
2. Root Terminal and Terminal both are there. Merge them into single terminal
3. Shotwell is photo manager. Also Eye of Genome is also present. Remove duplicate functionality.
4. Package manger should be clearly and purposefully merged in to single package.
Also there are some duplicated command line utility/application which should be merged or removed to gain space and to make this distro better.
