Main focus is on the UI/UX ecosystem since we have had extremely rocky waters recently with light wallets. Core repos like zcash/zcash and zcash/lightwalletd are basically upstream dependencies in this scenario. Not exactly a monorepo. I call it a metarepo. I much prefer to work on different repos in a defined layout with defined versions than have a whole mess of ad hoc checkouts of things. Try it out and let me know what you think!
Note the free2z/free2z metarepo will likely be renamed to free2z/zuu - ZUU is a play on “Zcash Wallet” and “Zcash UI Universe”. I’ll likely add the free2z source directly there without submodules and submodule some more things like zebra and zecpages there soon.
