The title pretty much says it all I think. Generally, I work at a specific horizontal zoom level when I'm doing manual repairs. It's really disorienting (for me at least) to do a repair and have the zoom level change.
I did look to see if this could be turned off but couldn't find anything...
We did this by request, and I have to say I rather like it. Would you give yourself a day or two to get used to it? If you still don't like it we will look into making it optional.
I'll give it a try :)
