Please make it possible to add gutter (margin) before the text area

Please consider making an option to add gutter before the text area to improve usability. Currently it is problematic to use the mouse to place the caret in the beginning of the line because there is no gutter to trap the mouse selection cursor: On the screenshot below I try to place the cursor before the dot, and need to be pixel-precise to make so.  Also I find it annoying when something "sticks" to the text/code, whether it is folding icons or line numbers (if folding is off) so I personally always want some extra margin to the left to improve readability. The setting could be named something like: "editor.leftMargin": 5, The number would indicate the margin width in characters, I suppose. In addition, an option to control how the mouse click behaves in this area should be added, I suggest "line selection" mode or "standard selection" mode. For "standard selection" a placeholder cursor would be shown just like in text. For "line selection" pointer cursor would be shown, like by clicking on the line number area.
