@ChakatStormCloud I second this! The ability to pin (and label) islands would be amazing.
In fact, any way to organize islands would be great. Color coding is a good start, but a few other options would be nice.
@SleepyAshsloth It's already possible, just use the tabs menu or the history menu.
Now, if you want to close a window and open days ahead from now, you can right click on the tab bar ans save the opened tabs to speed dial or pinboards
