I use subsequences a lot.
As soon as they are created I want to organize them, by naming & putting in relevant bin.
In Avid, as soon as you create a sub clip or subsequence (that use the *same* command/keyboard shortcut btw) and it creates the sub clip/sequence it selects the name entry ready for overtyping. Which is very useful.
It's also predictable where it puts subclip/sequence - in the last place you had it put them. Which is reset by holding alt as you make the subclip/sequence - where it offers a list of open bins, or 'create new bin' as an option.
In Premiere I create subsequence - which creates it loose in the project that the sequence is in, I think, and loads it into the source monitor (which I guess is useful to someone). I then have to 'reveal in project's to rename & move to the project&bin I want it in. Generally this is to a different project in the production - e.g. Gfx/Name supers or Gfx/locations or Sfx/WooshTransitions.
I guess this would be tricky in PP as all bins in a project are 'open' - which is why productions is a thing
90% of my work is in Premiere but I still miss some of the Avid features...)
