Gave it a 5-star review previously, optimistically thinking they might address the glaring conversion flow problems. Unfortunately the problems have persisted for a while, so thus it becomes the entire review: Please make it easier to edit the input when in conversion/units mode. It seems you can only change the amount (or use the calc etc.) if you completely exit the conversion mode. Itd be good to be able to select a conversion, pin it somewhere on the main calc display, and continue doing calculations while always seeing the converted result. More people should 1-star this thing until its fixed.
