Sometimes we see a good problem but we do not have an easy way to save it for later.

Now, poeple use bookmarks or notes , but that is not very comfortabl for them

My idea is :

-add a "To Do" button on every problem page.

-add a "To Do list" in the user profile with all saved problems.

-if the problem is solved, it is removed.

Alternative solution : a chrome extension that does the same thing.
