Hi Keith,
A quick search does not show this mentioned already: apologies if it’s a chestnut.
Project replace… does not find/replace text in the title of each entry (the title seen in the LH navigation panel, at the top of the main edit window, in the synopsis etc).
It would be nice to have this behavior changed because it’s a bit irritating after making a global change in the text to have to edit the titles/synopses individually.
Best wishes.
