Some questions - iPhone app

Thank you so much Richard for this excellent app - I'm enjoying the iPhone app as an addition to what was already my go-to routing site. I have a couple of app questions. Sorry if this gets a bit long!

- Does the iPhone app contextualise the icons at the bottom of the screen? Occasionally on the iPhone app I see a set of icons at the bottom of the screen relating to eg. time to destination, which I really like. But most of the time while I'm riding the bottom of the screen seems to be focused on only the next turn, even if that's quite far away. I haven't managed to get a good look at which icons are visible when, and I haven't found anything written down about what to expect at different stages, or how to change between them. Apologies if I've missed it but could you provide some explanation please?

- Have you thought at all about the option to customise the icons at the bottom of the screen? For example I'm very unlikely to ever need to look up accommodation in the app, and very rarely find a POI. Could these two valuable slots be used for something else?

And a couple of questions from my most recent ride, please tell me if you want this feedback through other routes. I realise these issues might be particular to city cycling, for example where there may be lots of equivalent routes:

- When I went off-route, and chose the "Reroute" button, the app seemed to lose my routing completely rather than just recalculate

- Is there any way to set defaults for what happens when you go off route? With gloves on I can't make a choice on the screen, so have to stop if I want the app to help me out. In most cases I would like it to reroute unless that increases the distance significantly.

- There is a road local to me which would be a great shortcut and the app often suggests it, but unfortunately, (a) it's a very steep narrow path and (2) it has no-cycling signs. It's Rock Hill, London SE26. I guess it's wrongly labelled in OSM?

- On my latest ride the app made a few odd suggestions on its choices for zig-zagging through grids of London residential streets - seeming to suggest longer routes when the shorter ones were essentially identical (eg. for traffic/surface etc). Is feedback on these of interest to you? I grabbed a screenshot of one in case that's helpful to you. Unfortunately it wasn't a saved route and the website isn't making the same suggestion if I ask again now.

- If I do choose a slightly different route for a short section, the app seems to want to take me back to the start of the deviation, even if I'm about to rejoin the original route. Is there a way to help it look ahead and see that our routes will converge?
