if you buy the premium version of titanium, you can restore all of your apps at once. using a nandroid backup would also restore your previous rom, so that method would not work if you are just trying to get the applications. homescreen layouts can be backed up/restored through some 3rd party launchers. i used ADW EX on my thunderbolt and use NOVA launcher on my GNex, both allow for it. i am sure other 3rd party launchers offer this feature as well, but the stock launcher will not do it.

 

Just pay for the donate version of Ti backup (if you're a flashaholic it's more than worth it). It will "batch restore" all the apps you choose to do so with

I'm careful of what I restore though. I only restore apps as "apps with data" can bork a flash or restore.

A "nandroid" = a "backup" if you meant that. Is there an app idk of called nanodroid?

 

You can do batch restores of apps with titanium. You might need the pro version to do this though, but it is well worth it.

 

yep, a nandroid is the same as a recovery backup. if you like the stock launcher, but want more features, i highly recommend NOVA. it is built directly from the ICS code only for ICS phones and looks/feels exactly the same as the stock launcher. the only difference is that there are many more customization options available.
