In the new download the progress is now split in 2 bars, download and patching. This is a good change and I like it but now you cant see the file change stats. In old steam you had the size stats from both download and patching, now in download I can see the absolute size
but the patching option only shows you the precent progress. I have the feeling that I worded the entire post like ♥♥♥♥ so here is a picture

the upper part says the progress in Gb downloaded/Gb total and the bottom in %, make both in absolute size and the % next to it

(I suck at explaining what im thinking don't judge the awful explanation of the idea)
