Can't seem to reset my coardboard

My cards are all “minimized” and I dont’ know how to reset the corkboard view. Please help?

Can you elaborate what you mean by minimized?

If you mean they are too small to read clearly, try the button in the bottom-right of the corkboard that looks like four index cards. If you can’t see that, use View/Layout/Show Footer View. That has numerous settings for card size.
