In order to get to the version of their character sheet they're most likely to want during play, a user has to go to their character profile in the main menu, and then select the sheet tab. Reloading that page resets the tab selection. If the user is on a mobile device (highly likely during play), this includes a lot of scrolling and extra tedium.
There is a page directly accessible from the menu that displays their character sheet and, as a bonus, shows less of the UI and thus leaves more space for the sheet itself. However, this only gives the display version of the sheet, making it less useful during play.
By making the character sheet page also include the tracker sheet, the player has better access and a better view of their sheet. The less of anything else on this page, the better.
WA on mobile devices is often... precarious. This would be one step towards making it a lot more useful for players.
