The problem

Sometimes i need to see the "Marks"
(symbols for Spaces, Tabs and/or End of Line markers)

But then again they disturb the view
the very next second and i have to
disable the view of this marks again quickly.
(For that there is an macro for your assistance
Toggle ALL marks at once (Space Tabs EOL EOF))


Suggestion

But i have seen an very nifty implementation
of displaying marks "just in time":

Have an option to show marks in selected text area!

That works this way:
- have the view of marks disabled
- have the option "Show Marks In Selection" set
- select an portion of text and see the marks at this block only




What do you think?
