This is relevant of image loading for histogram computation on right sidebar. 
I will fix it to use a separate thread to load image.

I don't understand what you mean. Please explain me better.

I will take a look . Any user report to remove this navigation widget. Any 
viewpoints about welcome.

idem.

Yes, i can reproduce it. Will be fixed later.

Hum, I need more viewpoints about...
