Back Button on Little Circle Icon Character Doesn't Do What You Expect

So, on the play screen, click one of the character or NPCs.

The nearly-full screen char opens.

There's a Back button.

I always want to click it to close down the character sheet and "go back to the play screen". But if I click it, it actually takes the page below the character sheet screen back one level in history (ie out of the game) but keeps the character sheet open. The x button on top right to close the screen does work, but it's not nearly as visible and tempting to click on.

I suggest making Back just close the sheet down and returning to the Play screen. Either that or maybe remove the Back entirely and force the user to use the top-right X to close the character sheet. Not sure which is better.
