Sorry for my poor English. I hope the translation software doesn't betray me too much or make me sound rude or picky.
Suppose I am editing line 230 of chapter 1 of an ePub.
Then I see that I need to look up or check something elsewhere in the book, so I search for a certain word or phrase.
If the search is successful and finds that phrase in another chapter, when I go back to chapter 1 to continue editing, I find the cursor on the first line of the file: I have lost the editing position.

If the search is unsuccessful, the cursor also goes to the beginning of the file.
I guess this must be a bug. I would like the cursor position not to be lost, except in the inevitable event that the search is successful in the same file I am editing, and in which case it would be helpful if there were a button to return to the previous cursor position.
Thanks for your amazing work.
