Hi
I remarked a curious thing. I have a group of ten saved searches, numbered from one to ten that I use quite frequently. I call this group with the filter "insé". It allows me to insert narrow no-break spaces in any French language EPUB.
I can export this group as a .json file using the "export" button of the Calibre editor. If I import it back, it will be displayed in
reverse order (from ten to one). Only after restarting Calibre will it appear in the right order (from one to ten).
This quirk may confuse some users. I do not know if I made a mistake somewhere. Experience tells me that this is surely what happens, but I fail to spot it.
