Caleb - we rarely need to water the leaves or flowers of garden plants - that isn't good for them - it's the soil around the roots that needs the water. Water on the leaves can cause scorch-marks when the sun shines, and watering the flowers can also damage them.
What I would find useful is a transparent watering with litres and millilitres etc marked clearly (like my kitchen measuring jug) so that when I'm adding something like soluble potash to the water to be watered into the soil, I can be more accurate if I want to use smaller amounts of water.
At the moment my watering cans hold about 2.5 litres of water each (I think) and I have to guess if I'm using small amounts of soluble fertiliser, or mix it in a kitchen measuring jug then tip it into the watering can.
