Needs decimal places for framerates

This app is brilliant and I use it all the time but I’m only giving it 4/5 stars because you can’t input decimals such as 23.98 or 29.97 or 59.94. You have to round off to the nearest whole number which is really annoying when I’m trying to be precise. Please add this feature, I’m sure it wouldn’t be that hard to implement.

Not specific enough frame rate options

I wish I could type in the specific frame rate up to three decimal points so that when shooting at 23.976 I can know for sure what angle should work.
