I often open itch and then immediately click on an item on the top bar (dashboard for instance)
and then I realized that some thing looked interesting in the game showcase. then I’m stuck refreshing the front page hoping that I can see that game again. having arrows to cycle the showcased game would be cool

There’s no way to cycle through it, but everything up there should also be something that shows up on grid on the homepage, so if you no longer see it in the top slot it should be somewhere below.
