I put an option in synedit.

It is not published in ide options (patch welcome). but you can edit it 
on top of synedit:

   TSynVisibleSpecialChar = (vscSpace, vscTabAtFirst, vscTabAtLast);

   SYNEDIT_DEFAULT_VISIBLESPECIALCHARS = [
     vscSpace,
     vscTabAtLast
   ];

property VisibleSpecialChars: TSynVisibleSpecialChars
