Hi. I am trying to override the navigational/horizontal menu theme for my site. The theme is Skyline Downtown. Three things I want to override:
1. remove the dots that indicate there is a second level of navigation.
2. Change the color and location of the selected state rule
3. Remove the blue rule that runs at the bottom of the menu

I accessed two .less files that I think I needed to work with:
A. constants.less
B. gadget.menu.horizontal.less

I made the changes in both.
I uploaded those files and then clicked the "rebuild themes" button. Nothing has changed. Any ideas please? The countless hours I have spent in trying to make these modifications are driving me mad. In the end I really want something as simple as this: http://shongumlake.org/ (made in WA) but I can't figure out what I am doing wrong.
