There is > even an option for cartouches. proper pretty printing should not be to difficult; maybe Sledgehammer_Isar_Proof can be reused or a common base extracted from that. explore_have should maybe just be the standard variant. I would suggest a further variant explore <method expr> would actually be the same as apply <method expr> but, given a proof goal ‹!!ys. Qs ==> D›, for remaining goals ‹!!xs1. Ps1 ==> C1› … ‹!!xsn. Psn ==> Cn› after method application suggest a proof skeleton proof - fix ys assume Qs have C1 if Ps1 for xs1 moreover have C2 if Ps2 for xs2 … moreover have Cn if Psn for xsn ultimately show D by qed <method expr> and hence provide a way to quickly get to the essence of a proof after initial »explore auto«.
