I would also like to see more features in the SD Card Player UI. What you are describing is a full feature Video Player App. To do this the Wyze App would need to be a lot larger and have some significant upgrades. I’m not sure the SD Card file structure is right for that either.
But, if you would like to request that Wyze add this feature, that is handled thru a new topic post in the Wishlist. Go to the Wishlist, search the topics for one that matches your request. If you find one, vote for it at the top, like 
some posts, and add your reply post to support the request. If you do not find a match, submit a new topic for approval.
