Good news - very good news, that I hope many of you will be happy to hear. Bookmarks and Navigator are now available for RAD Studio 11.
Full info here: https://blogs.embarcadero.com/bookmarks-and-navigator-are-available-for-rad-studio-11/
The blog post has full info but a couple of notes:
We have set up systems so this build delay should not happen again
They are available for both 11.0 and 11.1
The Debugger plugin is also coming within a few days
Many thanks for your patience here, and I hope you find installing these helps your productivity and use of the IDE.
