Next high, next low, and whether the gap is wide enough to launch

Pulls tide predictions for your nearest station and shows the next turn with a countdown. I kayak the estuary and mostly I just need to know if I have time to get out and back before the water turns. The bar fills as the window closes.

Owner — does the countdown jump to 'to low' once you pass high, or stay locked to the next high? Took me a second to realize 1h52m was to high, not the launch window itself.
I do the same out-and-back math in my head every evening, so a 'window: open/closed' verdict is genuinely useful. Would love a setting for my own safety margin — I want it to say closed earlier than slack.
The fill-bar-as-window-closes is such a clearer read than just a number. Which tide feed are you pulling — does it cover UK secondary ports or just the main stations?
