Scratchpad was specifically added as a feature to clearly allow people to use it Postman in an offline mode because otherwise people were confused about the distinction between an offline/online mode (Why is my content not showing up on Postman's web version for example). There are some features that just can't be developed with local storage as the only option.

An exceptionally large majority of users that give us feedback are pretty happy with the collaborative online features that we provide through Workspaces.

Unfortunately, a small but vocal minority is insistent that all those things be not developed because they have built their own workarounds through patterns from decades ago (CLIs, editors, repositories). I just don't agree with the sentiment that progress towards making lives easier for others should be stopped for a narrow viewpoint to be met. I also understand that it will lead to alternatives but so far almost everything that I have seen in the market has been a clone of our feature set - open source or closed source. I am happy to see people compete with new ideas.
