As tested in SL 1.9.0 RC1 (19030)

and

as discussed in
scratchlive.net
(also read the links of the links),

it makes sense to split the option "Protect Library" into "Protect Files" and "Protect Crates" because

- I don't want that SL makes updates (Protect Files = on)
and
- avoid adding overviews
- also there are currently bugs:
- that SL only writes tags back which it "knows" (others are removed)
- unclear when multi-tags like COMM will work
(Tag & Rename supports multi-tags and all my files have them)
(SL only reads/writes the first COMM tag which it finds - and writes it back wrong (if variable/value pair exists))

All the changes in the files changes the modify time stamp of my files. With the next SYNC with my backup all these files will be backuped again.

- I want to change my crates (Protect Crates = off)

It also makes sense to add an option "Don't write overviews". Maybe later I want to set "Protect Files=off" (if there are no bugs anymore) but I don't want that SL writes overviews in my files.

Thanks!
