Can you make it so that when I view a character in my campaign I can have a link to all the other information/characters in my campaign? As it is now, I have to jump back to the main page then link into the next character I need to examine. I would like to just browse the characters jumping directly from one to the other.

There is it already. on a character sheet, click on the button on the top right "Campaign". There is the list of the character, all linked.

But, truth be told, you can open the sheets in different tabs on your browser.

thanks! I did not think that was a clickable button!
