Description
As a help-seeking Squeak user, after clicking on a link from one help topic to another in the HelpBrowser, I want to be able to go back to the previously topic with one action, such as a button or a menu item, so that I do not have to retrieve the previous topic from the tree view on the left to find my way back.
Likewise it could make sense to also be able to go forward again, like in web browsers.
Example: search for a class name like "MorphicModel" in the Squeak Help, you will get several results from the topics that are auto-generated from the code, click on one of the "(open topic)" links. You will now be deep in the hierarchy, and to get back to your search results you must either search again or scroll down to the bottom of the tree view to get back to your search results. If you navigate from one deep node to another, it will be even harder to get back to the previous topic.
