modify an arrow size

[sugizo]

background
arrow is on the square and it can distract and divert attention

question
is it possible to modify an arrow size ?

some possible idea

• make an arrow full of path in svg, then it can change the fill (none (transparent) or other color value)
  or
  the stroke-width value (0 for disabe the stroke)
• make several arrows size, then can pass it as argument,
  e.g. big, moderate, small, etc

thanks and best regards
