In the new UI (which is generally an improvement), one thing has deteriorated: The confirmation screen when sending attacks. In all browsers/devices, but especially on a Mac, sending 4 waves using the "ctrl-tab" approach requires highlighting the confirmation button in 4 tabs. This used to be simple by clicking in the empty are above the buttons and pressing tab twice, which would clearly light up the confirmation button (allowing activation by pressing enter). Currently, the highlight is hardly visible (windows/firefox) or completely invisible (macos/firefox). This makes sending 4 wavers a really nasty experience now!
