Toggling coordinates on a mobile is a very uncomfortable. You have to quit the view of the board, scrolling fully down to access the toggle and then go back up to the view. There are 5 steps possible and you have to scroll up and down each time to check the result.
Could we have 1 button here :
I set coordinates exactly once per device. Are you really changing them that often we need to move them away from all the other menu items?
I agree that it’s annoying when someone posts coordinates in the forum or something and I just want to see what they are talking about, but I’m on mobile with coordinates disabled.
A quick toggle that doesn’t require scrolling back and forth five times would be really nice.
However, the controls @Groin mentioned are not visible by default either, so I’m not sure that’s a good place for the toggle.
I put away coordinates unless I need to use them or someone else. Just common practice, esthetics and small screen.
That’s what I see, I even don’t have to scroll to reach it
In a review or analysis, yes, but not during an active game, right? The worst case is probably during scoring.
That’s true, I haven’t considered these as in fact using coordinates is more linked to watching or reviews as playing.
Anyway I’m sure we can find a place in the page somewhere near the board.
Maybe you just need to adjust your browser settings? I can toggle coords and see the board at the same time just fine 
How you do that? I have to scroll down myself to reach the switch (and lose the sight of the board)
Hmm on further investigation it seems that’s a phone wide setting, which may be too extreme for your use case. However if you briefly flip your phone horizontal when you need to toggle coords it gives you a very adequate view IMO
Ok it’s a trick I didn’t think of (I never use this post stamp format for my board)
Oh yeah it’s totally unusable for playing haha but it’s handy for seeing board and chat sometimes, or also for settings as here.
You make me discover the usefulness of this landscape view 
If you remember I managed that democratic game on the forum, with thousands of posts and diagrams which should have or not have coordinates, and I just discover the trick thanks to you.
I hope it’s more useful on tablets 
really to be useful on mobile it should use the whole vertical space for the board and all menus and buttons should be moved to the sides. How it is now is impossible for mobile play haha
