Any update on the BTC support? I see the initial commit but nothing else.

We are developing it in the Beta version. It will be released shortly.

I see that you've added signTransaction to the bitcoin beta library. Wondering if you plan on supporting P2SH signing similar to Ledger's signP2SHTransaction() which allows signing transactions with custom redeemscripts?
