Changing The Font Used For Task Names

How do you change the font used for task names? I tried making the changes in Preferences, but nothing seemed to happen. What I need to do is use a heavier font (not larger) so that it stands out better.

Version 3.2.3246

If you meant the font used in the task table, you can change the font family in the settings. There are no options for the font weight, sorry.
