Suggestion is that in the profile, every user should have a notepad available, where they can put down some thoughts. This notepad can just be the simplest of text editors.
People can make use of it different ways. For example, I would like to use such a temporary place to write unfinished posts. Because sometimes it is not possible to finish the reply in one sitting. And it is difficult to abandon the post in the middle.
There could be several other uses to it, I am sure.
Since it will be a simple text editor therefore it won’t be a burden on GS server. Plus not everyone would be using such an option anyway.
