Improvements advisable

I like the program. Simple and straight. It fails keyboard navigation like "next/previous page" and "enter" for saving a card. Those kind of simple things would be very convenient.
What I am really missing is that the window is fixed. Its not possible to drag to enlarge a card size of make it smaller. Sometimes I have not that much space on your screen to keep the program open because the cards are too big than.
