Hi. Thanks very much.I was not aware of the shortcuts - that helps. However, I think that the request is still valid, because a 'quick swipe' on the button often doesn't get registered by the Samsung, or gets registered as 'scrolling', whilst a 'tap' is much easier to do and seems to get picked-up more easily by the touch-screen.

I agree with your request.

Are you aware of these shortcuts:
If you want a quick zoom in / out then just swipe up/down on the scale button. Also press and hold scale button for quick return to your 'home' scale.

I am using SD 3.3.2.20289 on Samsung Galaxy S5. It's a great tool. I have a suggestion :

When hitting the orange 'Scale' circle the Android version of SD does not automatically show the currently selected scale in the 'list' of scales. This functionality does work on the iPad version of SD. The issue is that, especially during flights, the next scale you want is probably 1 or 2 scales up or down from the one you are currently on, so the currently selected one should appear in the middle of the scale window. Otherwise, you have to scroll up from 1:2500 every time. That's an issue if, like me, you have the S5 in landscape mode, because the 'Scale' list only has space for 3 entries .. so it's somewhat 'fumbly' to get to the one you want, more so in turbulence.

Just wondering if this can be done for the Android one, or whether it's a limitation of the Android platform (since it works nicely on iPad) ?
