In case the issue is resolved there, you don't need to create a bug report. The change will be part of the next Markor update.)

Correlating edit to view position is very hard. Especially in a files with images etc. The best we can do is scroll to the same % as the edit mode. However this will be wrong as often as not

@harshad1 If not edit, just scroll to the end of the file, then change view mode. The bug also occurs
