just accruing git stashes in every repo I work on forever
After learning #Magit's "spin-off branch" feature, I no longer accumulate (and subsequently forget about) stashes.

These are a much better option for "ah, I'll need more work on these commits, let me put them aside for now".
Right @jfred, stashes are not the problem, and are still quite useful.
What this does is give a better option for "I need this (series of) commits to continue, but I now realise it's more work than I expected, so a branch is better and I want that to happen right now, get saved as a branch that knows its ancestry, so I can switch to work on something else".
