Hyper-efficient, effortless Rated 4 out of 5 stars
Nostalgy does more for my productivity than any other extension -- in fact, given how much I use it, more than most other software on my computer.
Responsiveness is immediate and it's effortless to use. The only enhancement I'd want is being able to customize the keyboard mappings (see the Discussion section for more).
Many thanks Alain!
