Recent Runs is missing now, but others have mentioned that already. Please bring it back.
Also, if you go to the main All Games page (where it defaults to Most Active Runners), change the sorting to something else like Most Runs, it will sort by that only on Page 1. If you click on to Page 2 to see the next highest in the list, it will default back to Most Active Runners and show you Page 2 by that method instead. So that's not working properly, in fact it used to tell you e.g. how many runs each game had but now it only says how many active runners there are.
I miss being able to see the number of notifications I had by the bell icon, not just that I had notifications at all.
The "Random Game" feature would be more useful if you could filter it somehow. For example I mostly just look at Sega Genesis games on this site, so if I could pull up a random Sega Genesis game only, that would be much better.
I had previously contacted DeeKnow on YouTube about his run and he said that he ran on a Model 2 Genesis. I don't have one myself for comparison (just the emulator). I asked Drum as well and he ran it on a Model 1, but actually has all three versions. So that's what I know.
