moove a plugin by a action on a other plugin with deplacement, delay, alpha, etc ...

Hi all,
i'm very new to krpano, and i want to do with something i have done with FPP, it's here:
http://www.gabrielacoca.fr/dernierpdg/mercredi/

my questions are:
* how can i make scrolling the plugins with a onover action ( like you can see if you go on "chambres et suites", i mean how can i make the plugins scroll down with a delay when onover, and scroll up with a delay when onout
* how can i in-light the plugin when onover ( like all the names of the rooms)
* how can i make appear and keep a image when onover - disappear when out. (like on the button 'chamber art deco", or on the thumbnails of the page)
I use now panotour 2.0 and i'm not sure if i can change that in file.xml or in file_skin.xml
Thanks to all.

Thanks Andrey, i have already see this function, but what i doesn't know is to move a other plugin than the one with the tween action, for example, if plugin-one is on over, them move the plugin-two, if you have a little bit of code, it can help. An other thing, i have seen that you have develop a guy for kr pano, i have download and install it, but i'm not able to work with it, the error message is "krpano loading failed", even when i try to open the example you give with. Thanks for you answer.

thanks Andrey, i will read carefully, like you tell me , and come back after .
