I noticed that there are only tabs for PC, Switch, and Wii.

Let's say, hypothetically, I was to do a run on the Xbox One version played on an Xbox Series S -- Where would I submit it?

Maybe there needs to be tabs added for the PS4 and Xbox One versions.

(And also have the newer consoles that can play the XboxOne/PS4 versions added as platforms?)

this was discussed when the leaderboard was split into platforms initially, however we did decide not to include xbox/ps4 as there were no valid runs at the time. the load times on xbox/ps4 are most similar to the switch, so submit runs under the switch category & we'll consider adding more tabs once more activity is generated. thanks!
