Search in System-Folders - NOT

[Ortwin]

Looking at quants example I came up with the following idea:

put (another) switch on the search-definition pane to limit the search to non System-folders or the other way round
to expand it to System-folders
Currently it has a switch to expand to the recycle bin (to include it in the search), it should handle the Templates andy maybe the Icons and Imported Items as well
