After updating my old Geany today I discovered the Overview Plugin with enormous joy. Thanks for that!
However I am also affected by this issue. After comparing with other files it seems that Overview is behaving worse the more are wrapped. For example I am editing a Latex file with 8000 words on 450 lines. I find, that Overview and my main editor view get very async as I scroll down: While I am in the middle of the file in main view, Overview shows the very end of the file.
@b4n @codebrainz This behaviour is unexpected, confusing and most surely unintended and since I think line wrapping (and my use case) is not uncommon, I would categorize this issue rather a bug than an enhancement.
