I like seeing buyer and seller shared penalties merged.
I think that it's not possible to implement dropdown menus at the wiki.
At mediation, the last trader to accept the suggestion is the one who decides when the payout is submitted so having different penalties depending on the delay seems something that Bisq can't enforce so I would remove it.
