You should make a telegram/slack if you haven't already. This can build a community around the project and help with efforts. Also for updates and news announcements.

What's the github repo for this? Not yet?

My suggestion: build a shared lib (CLI) and let the community write wallet GUIs. I'd love to do this given I can get ahold of some stake in the project.

Does this only happen with buy transactions? I placed an order to sell 1 BTC at 19.25 and the order was filled as 1 BTC for 19.125. This makes sense because the transaction fee of .65% is roughly .125 USD, 19.25 - .125 = 19.125. But when I order to buy 1 BTC at 19.1 was filled, it was filled as .99 BTC for 19.2649. Not only is the BTC lower, but the USD is higher too (just like you mentioned). But, this didn't happen for my sell order; it only happened for my buy order. So does this confusion only arise for buy orders?

To be more exact on my buy transaction:

Type	Description	Delta BTC	Delta USD	Total BTC	Total USD
Bought BTC	0.99 for 19.2649	0.993	-19.13	0.996	0.017

And not to mention that this exact transaction got filled twice! And I only placed an order to sell 1 BTC, but ended up buying 1.98 BTC and owing 19.12 USD (according to my currently displayed balance). Shed some light on that why don't ya.
