Another recent frustration with FamilySearch is that, previously, they would use web browser cookies or other mechanisms to remember your log-on credentials for a few days. They're still installing nine cookies for a total of 4.2MB of disk space, but the credentials are no longer retained and we have to log-on each visit. Sort of a pain.
Too, the FS source reference search facilities have never been exactly the greatest. Even if the record exists both at Ancestry.com and at FS (and not infrequently the record may be at Ancestry/Fold3 and not at FS), about 10% to 20% of the time I can't locate it at FS without finding the specific particulars at Ancestry first.
I admit that, as of late, most of my citations are from Ancestry.com...and Rob Pavey's "Sourcer" extension has made that effort much more efficient and consistent. If I also (or later) find the same cited reference at FS, I'll typically append an "also see" statement to the Ancestry citation with a link to the FS entry.
