Show Marks (Space Tabs EOL) in Selection only

I just realized that we can do that already at our own:

1.) Enable all (or the wanted) whitespace marks from menu “View > Marks”
2.) Go to menu “Tools > Properties for xxx Configuration”
3.) Click the [Display] tab and select “Returns, tabs, EOL”
4.) choose Text Color > Custom and set it to white
(or to your chosen background color, if not default), (of course you could also set the color to a light grey for example)
5.) close the dialog with the [OK] button

Now the marks are invisible on normal work, but visible on selection only.

To reset to default, just go to that setting dialog from step 4) again and click at [Default] instead.

Thanks for making EmEditor.
