Storing a tab creates a new list every time

[americankestrel]

Hi,
Not sure if this is a bug on my end but every time I store a new tab (I use the keyboard shortcut "Store selected tabs"), it creates a new list. I think it would be better if it added the new tab to the most recent unnamed list, like OneTab. Otherwise, it creates a lot of lists with just 1 tab in them.
Thanks!
