more free features
I wish there was the option of having more features with ads. One way you could do this is by having banner ads along the bottom, with a "close button" or "x" in the corner of the ad. if you were to close it, you would either have to get the pro version, or go without the additional features.
App:
In this economy, I would much rather have ads and more features, rather than having to pay for features that would help me.
