Seems really fast and snappy when I tried it, but already ran into multiple bugs within minutes of using it that makes it not usable for me. (Not meant as a harsh criticism, but just understand that it's early software, and I hope for it to improve and get good enough for daily uses.)<p>1. The always-visible scroll bars (both horizontal and vertical) on the text box makes it not possible to see what I am typing (the scrollbars cover it and the text field is not large enough to show both scrollbars and the text) -- this is on the Mac client. The same scrollbar issue exists on the channel list on the side as well, but at least it's not blocking anything.<p>2. When I sent a URL, the message immediately disappeared because Slack tried to generate the link preview, and apparently it's not supported yet in this client, so the whole message is just not shown.
