Having an in-app tutorial / help guide would make forced user documentation reading possible

[Col-E]

From Eclipse:

While useful by itself, for first time users forcing them to go through a simple process (unless they are VERY sure they want to skip) would inform users about how to use Recaf and some possible features they'd miss out on otherwise. Plus it could point out common problems like users not using a JDK and how to resolve the problem.

There should be a question mark icon in the window titlebar (if possible), like some certain old Windows applications, and on click, should provide you with a "help cursor" which then allows you to click on a UI element and open up the respective documentation for this part of Recaf directly in a tab inside of Recaf.
