Feature request: list separator

[AntonioGHub]

When the list of closed tabs becomes very long, it is easy for me to get lost looking at it.

Maybe a usability improvement could be to separate the batch of stashed tabs with just simple lines:

my tab 1
my tab 2
-----------------------------------------------
my tab 3
-----------------------------------------------
my tab 4
-----------------------------------------------

The separator could even be marked by date:

my tab 1
my tab 2
---------------------------------- 10 secs ago
my tab 3
my tab 4
my tab 5
---------------------------------- 20 mins ago
my tab 6
---------------------------- yesterday at 12:45
my tab 7
---------------------------- yesterday at 14:00
my tab 8
------------------------ 27 days ago, thu 2 jan
my tab 10
my tab 11

Thanks
