No. The Usb finder and resp. the Process finder look for hardware attached to, resp. processes running on, the local PC, so their scans are fast and without LAN involvement, so we deemed it not necessary to disable them.
I will check. EDIT: apparently ‘addons.cfg’ has absolutely no official doc for it. Or? So rather than just editing an existing file (which I could easily do), it would require creating a complete new page and linking it into the table of contents etc. => WDYT?
