Currently, several menu entries are missing in the context menu of the browser:
Open in file explorer
Copy pathname
Compare...
New folder
Print...
Batch Rename...
JPG Lossless transformations..

Notes:
- This is not a real bug. But differences in the user interface of XnView Classic and XnView MP are irritating and should be avoided whenever possible This is why I'm posting this as a bug.
- In some respects the menu of XnView MP might be better than XnView Classic, and in some respects the other way round. In first instance XnView MP should have the same menus as XnView Classic unless decided differently for both programs.
