- sats/BTC unit toggle on the on-chain amount field with live conversion
hint; canonical value stays sats end-to-end
- Fast / Standard / Slow fee presets (1 / 6 / 144 block targets) plus a
custom pane taking target blocks or an explicit sat/vB rate
- confirm pane shows LND's fee estimate for the chosen speed via the new
lnd.estimatefee RPC (GET /v1/transactions/fee)
- lnd.sendcoins now accepts target_conf / sat_per_vbyte with the same
mutual-exclusion + range validation as channel opens
