What plan for litecoinz? Why is best then bitcoinz, or zen, or hush, or komodo, or zcash, or zclassic, or bitcoin gold or any other on the equihash?

Zcash and many other currensies have fundamental problems:
* scalability, maybe you have play for liting network or analog?
* database size, maybe you have the garbage collector in the plan?
* the difficulty of confirming hidden transactions, any plan for it? (If all transactions on the network are hidden, confirmation will take forever)

I do not understand, LTCZ looks like scam, but have native GUI and have good fork (source code). Do you have plans for make changes
on core, or you want create only frontend?
