Simple but needed lock Size

maybe it just me but the fact that the viewer size cannot be locked is very annoying, a slight touch of the mouse in the viewer and it either shrinks or make the content huge. I like my footage to stay the same size i.e FIT.
Please can the powers that be add a padlock icon to lock the viewer window to the size the user sets.

Thanks

There is a separate forum for Feature Requests.

Best practice is to search first, to see if someone already asked. If not, post one idea per thread with a very brief description of the idea in the thread's title.
