How do I change the font for the emails I write? I went to that section under settings and it only will show "modern" font and "tiny" text. When I click the little arrow to select a different font or size, it does not bring up any options. One time when I tried it, I saw part of an option below but it could not be selected or seen.

I have a long correspondence with a person and when I click on the newest email, it does not always take me to that email. It takes me to a random place in our long list of email exchanges or takes me to a place where the emails get older going in BOTH UP OR DOWN DIRECTIONS. That is insane.
Can't you make it so I can scroll down to read the most recent email that I either sent or received? If so, HOW? Thanks
