Would be nice to have history of visited locations, at least for current session or better saved and restored with every run of Dolphin.

I was a bit disappointed that I wasn't able to back to previously visited directory otherwise than clicking several times in "Go back" button. To be honest. It was a bit annoying :/. 
I held the button "Go Back" and nothing happened, whereas I expected similar behavior like in web browsers.
I checked combo with path clicking in arrow down and after several changed of directory here always was present one entry :(.

I'm not sure if mentioned in subject function in present in Dolphin, but I wasn't able to find properly option in configuration which turns on this function.
In "Places -> Recently saved -> Today" I see only empty list, maybe the purpose for this is different then I expected and here are saved recently saved files in  some editor (Kate/KWrite).
