Good App - Nice Design - needs a tiny bit of polish...

This is a good app if slightly overpriced compared to the competition.
Watch out when scrolling a page as the variable sliders seem to attract focus and you end up moving one of them instead of the page... Extremely annoying to say the least...
Also I would have preferred a smaller font size and a more compact outlay and design in the main window in order to fit in all the info without having to scroll - The Hyperfocal Distance is at the bottom of the page and its a pain to have to scroll down to it - have a slider catch your finger swipe - readjust slider - and scroll down again...

So Mr Developer could we have 1 swipe fix and 1 refined outlay in next update please ?
