potentially useful scripts
Copy URL from clipboard and use dmenu to prompt for memo:
#!/bin/bash
later -q -t "$(xsel -b)" "$(dmenu -p memo: <&-)"
Pipe file into dmenu and open selected entry:
#!/bin/bash
if [[ -f "$1" ]]; then
FILE="$1"
else
FILE="$HOME/.later"
fi
later -q -O "$(dmenu -l 30 < $FILE)"
I bind both of the above scripts to keys using my window manager of choice.
Hopefully someone else will find this useful!

In a pinch, you could approximate what you're looking for by bookmarking all of your open tabs into a new folder in your bookmarks, then using the option to "Open in Tabs" when accessing that folder in the Bookmarks menu. That's certainly clumsy compared to a simple one-click "save state" method that you're requesting, but it's something....
