Hazel doesn't close tabs because it's 'like a trip down memory lane.' Mozilla says it has some profile and tab group features coming later this year that might help her organize those memories.
Same. It's just that my tasks tend to stretch multiple days and overlap, so there's rarely a clear cutoff.
I'm a software developer and team lead, so I'm often involved in two separate releases simultaneously, planning on one or two major features, and new development on another project, so I have tabs related to each. I try to make time every couple weeks to clear out a couple hundred tabs that have accumulated.
My workflow works for me though, and it feels real good to close hundreds of tabs knowing that one big project is finally finished.
