hey, good change, couple quick things if you don't mind (these are things i've meant to get to, and it'd be great if you could tack them on so i don't have to open this file lol):

• the bg color for the "hint" is off, should match the rest of the background (BackgroundPanel i believe); this applies to both the delete and new session hints
• can we swap the new and delete hints? new on the left, delete on the right
• you can use layout.Render to get a flex-like layout so you don't have to calc the space between manually; there's a JustifySpaceBetween (something like that)
