Looks good, small note that the "Open the logs folder" button won't work at all on Android right now. There's not really anything we can do about that for now though.

Actually, it's also worth considering that a lot of the time, the server won't connect via websocket at all, maybe there could be a timeout on the loading page? At least to indicate that nothing is happening, as otherwise people will sit on that page for hours.
