2 Questions: S2U2 Fun and Sktools Lite?

[Churka]

AS the title indicates, I have 2 questions.

I have Slide to Unlock, the latest version.
I set my own wallpaper and thats about it.
How can I further 'configure' or play with my S2U2.
I see custom buttons for the slider... etc, etc.



Second question. You know the 2 tabs at the bottom of the today screen that are 'launchers' kinda. They Calendar and Contacts as default.
How can I change those to what ever I want?
Example: Change contacts to open up IContacts.
I believe it can be done with SKtools Lite, but i have no idea.


Thanks in advance!
