Useful Great App- Needs Improvement

I like this application and it works really well for studying.
However, itd be nice if there was an option to check off whether or not you want that card to be seen again while studying.
I have to continually skip through cards I know very well to get to the ones I dont know as well, where Id rather just be able to take them out of that pile without having to delete them.
Not only that, but I think adding more personalization would be great--i.e. fonts, colors, etc. And some cards I have a lot of information that doesnt fully fit on that card, so maybe a scrolling option would be a good idea, that or just simply smaller font choices.
Thank you!
