Sure, I hope I can find something worth mentioning, as I can't really figure what plugins use those functions, and I myself use just the functions explained in examples provided on the forum.
I only remember seeing
db.get_metadata() before, because it is used in a search to find all items (e.g. authors) that have an attached note.
I'm currently testing some Action Chains and navigating the UI, everything seems to run smoothly.
BTW, those interested in testing on Windows can follow the steps below, although that's not recommended on a working/main library, please correct me as needed:
- download this file
https://github.com/kovidgoyal/calibr...ads/master.zip
- extract for instance to c:\users\username
then run the following calibre-dev.bat
set CALIBRE_DEVELOP_FROM=C:\users\username\calibre-master\src
start calibre
