Hello ;I would like to know if it's possible to configure the folder margin style or the code block !! as default it was an arrow and I would like if it's possible to make it like notepad++
I don't know what symbol notepad++ uses but try playing with the "Theme - Default" folder in your packages directory (preferences>browsse packages) to make theme changes.
thanks for your comment , you know it s near the number line , when you click there there are arrow which appear it makes to fold block code !!and I would like to change this arrow
