I totally agree! Having one huge library defeats the purpose of having multiple libraries to separate your work, makes the scanning and review of the uber-library tedious, and would have to slow operating times for searching, reports, etc. Espeically when you take it to the iPad environment.
I don’t see why the field is permanent once entered; it now refers to a library I no longer use? That library had errors and corrupted files (and 759 records). I’ve fixed it, and I want to be able to choose the correct library I’m working with (which currently has 126 records). Please open up that field and allow the old library to be replaced (on the web and/or iPad) with a library of one’s choosing!!!
