The ZOMG is now ZCG zcashcommunitygrants.org which evaluates grants and funds ecosystem development. CakeWallet’s status of adding ZEC support is still unclear, they haven’t officially submitted KYC docs to receive funding and add ZEC support to their multi-coin wallet. Trezor’s milestones are in progress, I believe they will resume the pending work following the NU5 upgrade. I am personally looking forward to testing UAs on Trezor Model-T.
As of now, it’s all a work in progress to get Orchard/UA support on Zcash user wallets. You can follow @NighthawkApps monthly updates for more info, the UX for Orchard is in preliminary steps as of now.
I am looking forward to learning more about the Orchard migration tool too!
