Nice app but missing few things like * adjusting crop auto/manual and filters, when using image to pdf editor option. * Adding few more filters can be useful. * Icon can be redisigned/simplified. * I like the app features offered by pub:Simple Design Ltd. * I have tried your app felt it has the potential to be much better. I am planning to switch to your app permanently if above features are implemented. - Thanks
