Hi all,

I have a Yes/No custom column named #fav, that I use in conjunction with Action Chains plugin (Single Field Edit) to set a star emblem in Cover Grid by pressing F, dedicated to store my favourite titles.

Today I wanted to see the date some title was added to Favourites, as if it were possible to sort those "bookmarks" the same way web browsers like Waterfox Classic do... then I noticed I couldn't. lol

So I think I need to create a new custom column of the type "built from other columns", that will look for the value stored in #fav and set the date that value was changed, is that correct?

I looked into the template language section of the Calibre docs, but couldn't figure out how to create that custom column. In fact, the only custom column I have of the "built from other columns" type is one that uses the {:'approximate_formats()'} function, which was easy to do as all it needed was a simple copy/paste from the manual.

BTW I learned the other day that the custom columns feature was contributed to Calibre by @chaley, thank you so much Mr. Haley.
