[orca-list] found Unity 2D extremely comfortable, just had few doubts

[hackingKK <hackingkk gmail com>]

Hello all,
Today I tryed Ubuntu precise and was very pleasantly  surprised to find 
it very comfortable to use.
I just have a couple of doubts and if cleared I think I will be ready to 
make a shift.
Firstly, I am extremely pleased that I could setup mobile broadband and 
wifi connections from the top panel.
I could also access the search bar and pressing the alt + f1 I managed 
to find a few apps in the menu.
However I wish to know if I could add few more apps to that menu and how?
I mean is there some keyboard shortcut or shortcuts which can help me 
add more apps to the menu that comes with alt + f1?
Another aspect I am interested is to change the order of the apps which 
I can access using the super key + numbers.
What if I wish firefox to be on the first position and then thunderbird?
Lastly, I wish to know if I feel comfortable with unity 2d? can I use 
Ubuntu 11.10 as of now to get used to the up coming 12.04?

Let's say if I use the latest Orca, Epiphany and other stuff on Ubuntu 
11.10, will I be good to go with it untill 12.04 is released?
Happy hacking.
