Tools

A portal tool search all problematic CMFFolder (e.g. oversized CMFFolder, CMFFolder with too many objects, CMFFolder with oversized objects)

You can update all the CMFFolders using the tool, or disable folderish setting here

Quota

The portlet shows the CMFFolder situation. The overflowed problems will be highlighted.
You can customize the quota count categories. John and Peter's objects are checked respectively in the screen dump.
Checking quota is easy, just put a "QuotaAW" instance into the folder you want to check quota.

Style

You can select the style for any folder

The sample:

Left and Right Slots

You can change the left_slots and right_slots for each folder. Putting "empty" will stop the use of the slot, Blank input will acquire slots from the parent. You can just input the slot macros like you do in the portal properties for left_slots and right_slots
