Show last Render option - same as in the production renderer [show las VFB]

[3DMK]

Would it be possible to have a show last render option the same as in the production renderer??? [Show last VFB]

I'm sure there are many other more important things so don't put it too high on the list.....it is mainly helpful for forgetfull people like me...lol.. who want to have another look after forgetting to duplicate or save the RT image

Cheers
Jamie
