I am studying the Mylyn of the Eclipse IDE and I came across the "Mark as Landmark" option that appears available for some < in> Package Explorer , and I had some doubts about what this is, what it is for, and how to use it:
In the above gif, I have an Active Task, and the Package Explorer has the option "Focus on Active Task" linked, from that I do the following actions:
Main.java with the right mouse button and check that the "Mark as Landmark" option is not available for it; Why is it unavailable?
[+] button to the right of the Main.java file so that the "children" of it that are not part of the Context are displayed, and then the Main ( 
)thatisinsidetheArchive;Mainthatappeared,andrightclickonit,seethatthereistheoptionfor"Mark as Landmark" ; [+] and the "children" of it that are not part of Context are displayed, which are: the Main ( 
), the UI method ( 
)andthemain(String[])method( 
);start(Stage)thatwereopenedinthepreviousaction,youhavethe"Mark as Landmark" option available, but in the gif I show this only for the Main , by clicking on it with the right mouse button; main(String[]) method to be checked, note that it has been bolded; main(String[]) method, looking for an option to deselect it as "Landmark", but I can not find it! and the "Mark as Landmark" option is still available for it already being marked (why? it will be a bug?). How can I unmark the item as a Landmark? Key Questions:
- The "Mark as Landmark" option appears to be only available for Items that are part of the Context Active Task, so I think it's a Mylyn Tasks system Contexts system; Is that right?
- What is and / or what is the Mark as Landmark option?
- In what cases is it interesting to use the "Mark as Landmark"
- How to properly use the Mark as Landmark option ?
