I really like this however I've already had some issues with the double click feature.
I can apparently only double click once on the viewer window, any other attempts just makes the text blue and doesn't swap to the editor.
Other times it goes grey but the cursor is then put onto the wrong line
Sometimes it goes grey but I don't see the cursor at all and the viewer puts a highlight onto a different line.
One potential feature request (not sure if it is even possible), could the double click feature be used on the single pane viewer to take you to the editor pane? (or does it already do this and it isn't working for me?) This would be great for working like I would with the dual pane viewer but on devices with more limited screen estate.
I'm on Joplin 2.5.1 on Win10.
