option to switch on/off permanent display of folder sizes.
option to switch on/off permanent display of folder sizes, instead of having to select all and request info which dissapears when one moves on.
Also allow to navigate immediately to a favoutite, without having to confirm.

This cannot be done without a major performance hit.
You need to understand that there is no such thing as "folder size."
The thing you know as "folder size" is actually the sum of the sizes of every file reachable within a given directory tree. To get this number, the program needs to examine every single file and directory that exists under that particular directory, which can take a really, REALLY long time and if it's a complex directory tree.This is why "folder sizes" are only computed on user request in practically every system with a traditional hierarchical filesystem.
If you want to find out where your storage space has gone, you should use a specialized program, such as "DiskUsage" for Android, Baobab for GNU/Linux, WinDirStat for Windows or Disk Inventory X for OS X.
I personally prefer the commandline utility "ncdu" for GNU/Linux and other unices.
