[Feature request] Show execution time in history list?

Sometimes it's interesting to know how long workflow took to run. Esp if you know that its gonna be long, and you leave, would be nice to have ability to run one, tweak, run. See which one took longer, this would allow to eval if some tweaks are "worth it". Also to help with this, naming current workflow would be nice too, so that in history you see something like `experiment 1 (30s)` `experiment 2 absurdres (5m)` and similar.
