So this is a little one but has definitely allowed me to remove a rather annoying step to managing my email on my i-phone.
I just realized that in the i-phone settings, there is an option to turn off the "ask before deleting" option. I-phone is automatically set-up to ask you if you are sure you want to delete even after you've hit the "delete" button.
I don't know about you but when I choose to delete something I am pretty sure I want to delete it and I don't need to be asked if I actually want to delete. So, as a result, I have turned off the "ask before delete" button and now I can delete freely without interruption.
Yes, it's the little things that make the difference :)
