When tweaking render speed and sampling, it is really annoying that the text in the info bar (how much time the render took for how many samples) immediately goes away when sampling is finished. Also we only get an approximated time how long the render will take, but when finished you never see how much time it actually took. I think this really is a minor request because all the info is there, it just needs to be made available better.
I fear sth like a framebuffer with history is maybe too much to ask and I also like the idea that Vred can live without one. But it would still be great to have some kind of temp history and the possibility to compare current and previous renderings.
