TYPO3 Core

I have the following filemount structure:

+ rootlevel (readonly for all groups)
  + shared dir (writeable for all)
  + group 1 (writable for the according group)
  + group 2 (like group 1)
  + etc.

This results in 3 mounts for each group:
rootlevel, shared dir, "write protected" mount

Imagine this as some kind of simple shared directory layout, so files can be made available read only for other groups and to have a shared working directory. They are all set up in a non-public storage and not accessible from the outside.

We could of course add all group level directories as seperate mounts, but this kind of blows up the list of mounts in the file module with a growing number of groups.

+ shared dir
+ group 1
+ rootlevel

The tree already recognizes the write possibility for subfolders and does not add the lock icon to subfolders in rootlevel. But when folders are clicked to expand, not the ones that were clicked are expanded, but the first ones in the whole tree, same goes for collapsing.
