Feature Request: Click to Set & Then Easily Navigate Bookmark points within the Open File's text?

[amiga-500]

For whatever reason, i notice most linux editors seem to have an aversion for including what is pretty much a standard (and obvious) feature on many Windows editors: the ability to simply click the left-corner margin within an open file which sets a visual bookmark point and then use toolbar navigation arrows (or shortcut keys) to jump to those bookmark points. Makes it so much more easier and logical to navigate to key points in a file.
